type put_request = {
  1. item : (string * attribute_value) list;
    (*

    A map of attribute name to attribute values, representing the primary key of an item to be processed by PutItem. All of the table's primary key attributes must be specified, and their data types must match those of the table's key schema. If any attributes are present in the item that are part of an index key schema for the table, their types must match the index key schema.

    *)
}

Represents a request to perform a PutItem operation on an item.

type delete_request = {
  1. key : (string * attribute_value) list;
    (*

    A map of attribute name to attribute values, representing the primary key of the item to delete. All of the table's primary key attributes must be specified, and their data types must match those of the table's key schema.

    (*

    A request to perform a DeleteItem operation.

    *)
  2. put_request : put_request option;
    (*

    A request to perform a PutItem operation.

    *)
}

Represents an operation to perform - either DeleteItem or PutItem. You can only request one of these operations, not both, in a single WriteRequest. If you do need to perform both of these operations, you need to provide two separate WriteRequest objects.

type time_to_live_specification = {
  1. attribute_name : string;
    (*

    The name of the TTL attribute used to store the expiration time for items in the table.

    *)
  2. enabled : bool;
    (*

    Indicates whether TTL is to be enabled (true) or disabled (false) on the table.

    *)
}

Represents the settings used to enable or disable Time to Live (TTL) for the specified table.

type update_time_to_live_output = {
  1. time_to_live_specification : time_to_live_specification option;
    (*

    Represents the output of an UpdateTimeToLive operation.

    *)
}
type update_time_to_live_input = {
  1. time_to_live_specification : time_to_live_specification;
    (*

    Represents the settings used to enable or disable Time to Live for the specified table.

    *)
  2. table_name : string;
    (*

    The name of the table to be configured. You can also provide the Amazon Resource Name (ARN) of the table in this parameter.

    *)
}

Represents the input of an UpdateTimeToLive operation.

type resource_not_found_exception = {
  1. message : string option;
    (*

    The resource which is being requested does not exist.

    *)
}

The operation tried to access a nonexistent table or index. The resource might not be specified correctly, or its status might not be ACTIVE.

type resource_in_use_exception = {
  1. message : string option;
    (*

    The resource which is being attempted to be changed is in use.

    *)
}

The operation conflicts with the resource's availability. For example, you attempted to recreate an existing table, or tried to delete a table currently in the CREATING state.

type limit_exceeded_exception = {
  1. message : string option;
    (*

    Too many operations for a given subscriber.

    *)
}

There is no limit to the number of daily on-demand backups that can be taken.

For most purposes, up to 500 simultaneous table operations are allowed per account. These operations include CreateTable, UpdateTable, DeleteTable,UpdateTimeToLive, RestoreTableFromBackup, and RestoreTableToPointInTime.

When you are creating a table with one or more secondary indexes, you can have up to 250 such requests running at a time. However, if the table or index specifications are complex, then DynamoDB might temporarily reduce the number of concurrent operations.

When importing into DynamoDB, up to 50 simultaneous import table operations are allowed per account.

There is a soft account quota of 2,500 tables.

GetRecords was called with a value of more than 1000 for the limit request parameter.

More than 2 processes are reading from the same streams shard at the same time. Exceeding this limit may result in request throttling.

type attribute_action =
  1. | DELETE
  2. | PUT
  3. | ADD
type attribute_value_update = {
  1. action : attribute_action option;
    (*

    Specifies how to perform the update. Valid values are PUT (default), DELETE, and ADD. The behavior depends on whether the specified primary key already exists in the table.

    If an item with the specified Key is found in the table:

    • PUT - Adds the specified attribute to the item. If the attribute already exists, it is replaced by the new value.

    • DELETE - If no value is specified, the attribute and its value are removed from the item. The data type of the specified value must match the existing value's data type.

      If a set of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set [a,b,c] and the DELETE action specified [a,c], then the final attribute value would be [b]. Specifying an empty set is an error.

    • ADD - If the attribute does not already exist, then the attribute and its values are added to the item. If the attribute does exist, then the behavior of ADD depends on the data type of the attribute:

      • If the existing attribute is a number, and if Value is also a number, then the Value is mathematically added to the existing attribute. If Value is a negative number, then it is subtracted from the existing attribute.

        If you use ADD to increment or decrement a number value for an item that doesn't exist before the update, DynamoDB uses 0 as the initial value.

        In addition, if you use ADD to update an existing item, and intend to increment or decrement an attribute value which does not yet exist, DynamoDB uses 0 as the initial value. For example, suppose that the item you want to update does not yet have an attribute named itemcount, but you decide to ADD the number 3 to this attribute anyway, even though it currently does not exist. DynamoDB will create the itemcount attribute, set its initial value to 0, and finally add 3 to it. The result will be a new itemcount attribute in the item, with a value of 3.

      • If the existing data type is a set, and if the Value is also a set, then the Value is added to the existing set. (This is a set operation, not mathematical addition.) For example, if the attribute value was the set [1,2], and the ADD action specified [3], then the final attribute value would be [1,2,3]. An error occurs if an Add action is specified for a set attribute and the attribute type specified does not match the existing set type.

        Both sets must have the same primitive data type. For example, if the existing data type is a set of strings, the Value must also be a set of strings. The same holds true for number sets and binary sets.

      This action is only valid for an existing attribute whose data type is number or is a set. Do not use ADD for any other data types.

    If no item with the specified Key is found:

    • PUT - DynamoDB creates a new item with the specified primary key, and then adds the attribute.
    • DELETE - Nothing happens; there is no attribute to delete.
    • ADD - DynamoDB creates a new item with the supplied primary key and number (or set) for the attribute value. The only data types allowed are number, number set, string set or binary set.

For the UpdateItem operation, represents the attributes to be modified, the action to perform on each, and the new value for each.

You cannot use UpdateItem to update any primary key attributes. Instead, you will need to delete the item, and then use PutItem to create a new item with new attributes.

    *)
  2. comparison_operator : comparison_operator option;
    (*

    A comparator for evaluating attributes in the AttributeValueList. For example, equals, greater than, less than, etc.

    The following comparison operators are available:

    EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN

    The following are descriptions of each comparison operator.

    • EQ : Equal. EQ is supported for all data types, including lists and maps.

      AttributeValueList can contain only one AttributeValue element of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.

    • NE : Not equal. NE is supported for all data types, including lists and maps.

      AttributeValueList can contain only one AttributeValue of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.

    • LE : Less than or equal.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • LT : Less than.

      AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • GE : Greater than or equal.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • GT : Greater than.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • NOT_NULL : The attribute exists. NOT_NULL is supported for all data types, including lists and maps.

      This operator tests for the existence of an attribute, not its data type. If the data type of attribute "a" is null, and you evaluate it using NOT_NULL, the result is a Boolean true. This result is because the attribute "a" exists; its data type is not relevant to the NOT_NULL comparison operator.

    • NULL : The attribute does not exist. NULL is supported for all data types, including lists and maps.

      This operator tests for the nonexistence of an attribute, not its data type. If the data type of attribute "a" is null, and you evaluate it using NULL, the result is a Boolean false. This is because the attribute "a" exists; its data type is not relevant to the NULL comparison operator.

    • CONTAINS : Checks for a subsequence, or value in a set.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is of type String, then the operator checks for a substring match. If the target attribute of the comparison is of type Binary, then the operator looks for a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS"), then the operator evaluates to true if it finds an exact match with any member of the set.

      CONTAINS is supported for lists: When evaluating "a CONTAINS b", "a" can be a list; however, "b" cannot be a set, a map, or a list.

    • NOT_CONTAINS : Checks for absence of a subsequence, or absence of a value in a set.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is a String, then the operator checks for the absence of a substring match. If the target attribute of the comparison is Binary, then the operator checks for the absence of a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS"), then the operator evaluates to true if it does not find an exact match with any member of the set.

      NOT_CONTAINS is supported for lists: When evaluating "a NOT CONTAINS b", "a" can be a list; however, "b" cannot be a set, a map, or a list.

    • BEGINS_WITH : Checks for a prefix.

      AttributeValueList can contain only one AttributeValue of type String or Binary (not a Number or a set type). The target attribute of the comparison must be of type String or Binary (not a Number or a set type).

    • IN : Checks for matching elements in a list.

      AttributeValueList can contain one or more AttributeValue elements of type String, Number, or Binary. These attributes are compared against an existing attribute of an item. If any elements of the input are equal to the item attribute, the expression evaluates to true.

    • BETWEEN : Greater than or equal to the first value, and less than or equal to the second value.

      AttributeValueList must contain two AttributeValue elements of the same type, either String, Number, or Binary (not a set type). A target attribute matches if the target value is greater than, or equal to, the first element and less than, or equal to, the second element. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not compare to {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}

    *)
  3. exists : bool option;
    (*

    Causes DynamoDB to evaluate the value before attempting a conditional operation:

    • If Exists is true, DynamoDB will check to see if that attribute value already exists in the table. If it is found, then the operation succeeds. If it is not found, the operation fails with a ConditionCheckFailedException.
    • If Exists is false, DynamoDB assumes that the attribute value does not exist in the table. If in fact the value does not exist, then the assumption is valid and the operation succeeds. If the value is found, despite the assumption that it does not exist, the operation fails with a ConditionCheckFailedException.

    The default setting for Exists is true. If you supply a Value all by itself, DynamoDB assumes the attribute exists: You don't have to set Exists to true, because it is implied.

    DynamoDB returns a ValidationException if:

    • Exists is true but there is no Value to check. (You expect a value to exist, but don't specify what that value is.)
    • Exists is false but you also provide a Value. (You cannot expect an attribute to have a value, while also expecting it not to exist.)

    *)
}

Represents a condition to be compared with an attribute value. This condition can be used with DeleteItem, PutItem, or UpdateItem operations; if the comparison evaluates to true, the operation succeeds; if not, the operation fails. You can use ExpectedAttributeValue in one of two different ways:

  • Use AttributeValueList to specify one or more values to compare against an attribute. Use ComparisonOperator to specify how you want to perform the comparison. If the comparison evaluates to true, then the conditional operation succeeds.
  • Use Value to specify a value that DynamoDB will compare against an attribute. If the values match, then ExpectedAttributeValue evaluates to true and the conditional operation succeeds. Optionally, you can also set Exists to false, indicating that you do not expect to find the attribute value in the table. In this case, the conditional operation succeeds only if the comparison evaluates to false.

Value and Exists are incompatible with AttributeValueList and ComparisonOperator. Note that if you use both sets of parameters at once, DynamoDB will return a ValidationException exception.

    You would first need to specify ExpressionAttributeValues as follows:

    { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

    You could then use these values in an expression, such as this:

    ProductStatus IN (:avail, :back, :disc)

  3. expression_attribute_names : (string * string) list option;

    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

    • To access an attribute whose name conflicts with a DynamoDB reserved word.
    • To create a placeholder for repeating occurrences of an attribute name in an expression.
    • To prevent special characters in an attribute name from being misinterpreted in an expression.

    Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

    • Percentile

    The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide.) To work around this, you could specify the following for ExpressionAttributeNames:

    • {"#P":"Percentile"}

    You could then use this substitution in an expression, as in this example:

    • #P = :val

    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

    *)
  5. update_expression : string option;
    (*

    An expression that defines one or more attributes to be updated, the action to be performed on them, and new values for them.

    The following action values are available for UpdateExpression.

    • SET - Adds one or more attributes and values to an item. If any of these attributes already exist, they are replaced by the new values. You can also use SET to add or subtract from an attribute that is of type Number. For example: SET myNum = myNum + :val

      SET supports the following functions:

      • if_not_exists (path, operand) - if the item does not contain an attribute at the specified path, then if_not_exists evaluates to operand; otherwise, it evaluates to path. You can use this function to avoid overwriting an attribute that may already be present in the item.
      • list_append (operand, operand) - evaluates to a list with a new element added to it. You can append the new element to the start or the end of the list by reversing the order of the operands.

      These function names are case-sensitive.

    • REMOVE - Removes one or more attributes from an item.

    • ADD - Adds the specified value to the item, if the attribute does not already exist. If the attribute does exist, then the behavior of ADD depends on the data type of the attribute:

      • If the existing attribute is a number, and if Value is also a number, then Value is mathematically added to the existing attribute. If Value is a negative number, then it is subtracted from the existing attribute.

        If you use ADD to increment or decrement a number value for an item that doesn't exist before the update, DynamoDB uses 0 as the initial value.

        Similarly, if you use ADD for an existing item to increment or decrement an attribute value that doesn't exist before the update, DynamoDB uses 0 as the initial value. For example, suppose that the item you want to update doesn't have an attribute named itemcount, but you decide to ADD the number 3 to this attribute anyway. DynamoDB will create the itemcount attribute, set its initial value to 0, and finally add 3 to it. The result will be a new itemcount attribute in the item, with a value of 3.

      • If the existing data type is a set and if Value is also a set, then Value is added to the existing set. For example, if the attribute value is the set [1,2], and the ADD action specified [3], then the final attribute value is [1,2,3]. An error occurs if an ADD action is specified for a set attribute and the attribute type specified does not match the existing set type.

        Both sets must have the same primitive data type. For example, if the existing data type is a set of strings, the Value must also be a set of strings.

      The ADD action only supports Number and set data types. In addition, ADD can only be used on top-level attributes, not nested attributes.

    • DELETE - Deletes an element from a set.

      If a set of values is specified, then those values are subtracted from the old set. For example, if the attribute value was the set [a,b,c] and the DELETE action specifies [a,c], then the final attribute value is [b]. Specifying an empty set is an error.

      The DELETE action only supports set data types. In addition, DELETE can only be used on top-level attributes, not nested attributes.

    You can have many actions in a single expression, such as the following: SET a=:value1, b=:value2 DELETE :value3, :value4, :value5

    *)
  7. return_consumed_capacity : return_consumed_capacity option;
  8. return_values : return_value option;
    (*

    Use ReturnValues if you want to get the item attributes as they appear before or after they are successfully updated. For UpdateItem, the valid values are:

    • NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)
    • ALL_OLD - Returns all of the attributes of the item, as they appeared before the UpdateItem operation.
    • UPDATED_OLD - Returns only the updated attributes, as they appeared before the UpdateItem operation.
    • ALL_NEW - Returns all of the attributes of the item, as they appear after the UpdateItem operation.
    • UPDATED_NEW - Returns only the updated attributes, as they appear after the UpdateItem operation.

    There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

    The values returned are strongly consistent.

Recommended Settings

This is a general recommendation for handling the TransactionInProgressException. These settings help ensure that the client retries will trigger completion of the ongoing TransactWriteItems request.

  • Set clientExecutionTimeout to a value that allows at least one retry to be processed after 5 seconds have elapsed since the first attempt for the TransactWriteItems operation.
  • Set socketTimeout to a value a little lower than the requestTimeout setting.
  • requestTimeout should be set based on the time taken for the individual retries of a single HTTP request for your use case, but setting it to 1 second or higher should work well to reduce chances of retries and TransactionInProgressException errors.
  • Use exponential backoff when retrying and tune backoff if needed.

Assuming default retry policy, example timeout settings based on the guidelines above are as follows:

Example timeline:

  • 0-1000 first attempt
  • 1000-1500 first sleep/delay (default retry policy uses 500 ms as base delay for 4xx errors)
  • 1500-2500 second attempt
  • 2500-3500 second sleep/delay (500 * 2, exponential backoff)
  • 3500-4500 third attempt
  • 4500-6500 third sleep/delay (500 * 2^2)
  • 6500-7500 fourth attempt (this can trigger inline recovery since 5 seconds have elapsed since the first attempt reached TC)

type transaction_canceled_exception = {
  1. cancellation_reasons : cancellation_reason list option;
    (*

    A list of cancellation reasons.

    *)
  2. message : string option;
}

The entire transaction request was canceled.

DynamoDB cancels a TransactWriteItems request under the following circumstances:

  • A condition in one of the condition expressions is not met.
  • A table in the TransactWriteItems request is in a different account or region.
  • More than one action in the TransactWriteItems operation targets the same item.
  • There is insufficient provisioned capacity for the transaction to be completed.
  • An item size becomes too large (larger than 400 KB), or a local secondary index (LSI) becomes too large, or a similar validation error occurs because of changes made by the transaction.
  • There is a user error, such as an invalid data format.
  • There is an ongoing TransactWriteItems operation that conflicts with a concurrent TransactWriteItems request. In this case the TransactWriteItems operation fails with a TransactionCanceledException.

DynamoDB cancels a TransactGetItems request under the following circumstances:

  • There is an ongoing TransactGetItems operation that conflicts with a concurrent PutItem, UpdateItem, DeleteItem or TransactWriteItems request. In this case the TransactGetItems operation fails with a TransactionCanceledException.
  • A table in the TransactGetItems request is in a different account or region.
  • There is insufficient provisioned capacity for the transaction to be completed.
  • There is a user error, such as an invalid data format.

If using Java, DynamoDB lists the cancellation reasons on the CancellationReasons property. This property is not set for other languages. Transaction cancellation reasons are ordered in the order of requested items, if an item has no error it will have None code and Null message.

Cancellation reason codes and possible error messages:

  • No Errors:

    • Code: None
    • Message: null

  • Conditional Check Failed:

    • Code: ConditionalCheckFailed
    • Message: The conditional request failed.

  • Item Collection Size Limit Exceeded:

    • Code: ItemCollectionSizeLimitExceeded
    • Message: Collection size exceeded.

  • Transaction Conflict:

    • Code: TransactionConflict
    • Message: Transaction is ongoing for the item.

type transact_write_items_input = {
  1. client_request_token : string option;
    (*

    Providing a ClientRequestToken makes the call to TransactWriteItems idempotent, meaning that multiple identical calls have the same effect as one single call.

    Although multiple identical calls using the same client request token produce the same result on the server (no side effects), the responses to the calls might not be the same. If the ReturnConsumedCapacity parameter is set, then the initial TransactWriteItems call returns the amount of write capacity units consumed in making the changes. Subsequent TransactWriteItems calls with the same client token return the number of read capacity units consumed in reading the item.

    A client request token is valid for 10 minutes after the first request that uses it is completed. After 10 minutes, any request with the same client token is treated as a new request. Do not resubmit the same request with the same client token for more than 10 minutes, or the result might not be idempotent.

type condition = {
  1. comparison_operator : comparison_operator;
    (*

    A comparator for evaluating attributes. For example, equals, greater than, less than, etc.

    The following comparison operators are available:

    EQ | NE | LE | LT | GE | GT | NOT_NULL | NULL | CONTAINS | NOT_CONTAINS | BEGINS_WITH | IN | BETWEEN

    The following are descriptions of each comparison operator.

    • EQ : Equal. EQ is supported for all data types, including lists and maps.

      AttributeValueList can contain only one AttributeValue element of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.

    • NE : Not equal. NE is supported for all data types, including lists and maps.

      AttributeValueList can contain only one AttributeValue of type String, Number, Binary, String Set, Number Set, or Binary Set. If an item contains an AttributeValue of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not equal {"NS":["6", "2", "1"]}.

    • LE : Less than or equal.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • LT : Less than.

      AttributeValueList can contain only one AttributeValue of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • GE : Greater than or equal.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • GT : Greater than.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not equal {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}.

    • NOT_NULL : The attribute exists. NOT_NULL is supported for all data types, including lists and maps.

      This operator tests for the existence of an attribute, not its data type. If the data type of attribute "a" is null, and you evaluate it using NOT_NULL, the result is a Boolean true. This result is because the attribute "a" exists; its data type is not relevant to the NOT_NULL comparison operator.

    • NULL : The attribute does not exist. NULL is supported for all data types, including lists and maps.

      This operator tests for the nonexistence of an attribute, not its data type. If the data type of attribute "a" is null, and you evaluate it using NULL, the result is a Boolean false. This is because the attribute "a" exists; its data type is not relevant to the NULL comparison operator.

    • CONTAINS : Checks for a subsequence, or value in a set.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is of type String, then the operator checks for a substring match. If the target attribute of the comparison is of type Binary, then the operator looks for a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS"), then the operator evaluates to true if it finds an exact match with any member of the set.

      CONTAINS is supported for lists: When evaluating "a CONTAINS b", "a" can be a list; however, "b" cannot be a set, a map, or a list.

    • NOT_CONTAINS : Checks for absence of a subsequence, or absence of a value in a set.

      AttributeValueList can contain only one AttributeValue element of type String, Number, or Binary (not a set type). If the target attribute of the comparison is a String, then the operator checks for the absence of a substring match. If the target attribute of the comparison is Binary, then the operator checks for the absence of a subsequence of the target that matches the input. If the target attribute of the comparison is a set ("SS", "NS", or "BS"), then the operator evaluates to true if it does not find an exact match with any member of the set.

      NOT_CONTAINS is supported for lists: When evaluating "a NOT CONTAINS b", "a" can be a list; however, "b" cannot be a set, a map, or a list.

    • BEGINS_WITH : Checks for a prefix.

      AttributeValueList can contain only one AttributeValue of type String or Binary (not a Number or a set type). The target attribute of the comparison must be of type String or Binary (not a Number or a set type).

    • IN : Checks for matching elements in a list.

      AttributeValueList can contain one or more AttributeValue elements of type String, Number, or Binary. These attributes are compared against an existing attribute of an item. If any elements of the input are equal to the item attribute, the expression evaluates to true.

    • BETWEEN : Greater than or equal to the first value, and less than or equal to the second value.

      AttributeValueList must contain two AttributeValue elements of the same type, either String, Number, or Binary (not a set type). A target attribute matches if the target value is greater than, or equal to, the first element and less than, or equal to, the second element. If an item contains an AttributeValue element of a different type than the one provided in the request, the value does not match. For example, {"S":"6"} does not compare to {"N":"6"}. Also, {"N":"6"} does not compare to {"NS":["6", "2", "1"]}

    One or more values to evaluate against the supplied attribute. The number of values in the list depends on the ComparisonOperator being used.

    For type Number, value comparisons are numeric.

    String value comparisons for greater than, equals, or less than are based on ASCII character code values. For example, a is greater than A, and a is greater than B. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

    For Binary, DynamoDB treats each byte of the binary data as unsigned when it compares binary values.

    *)
}

Represents the selection criteria for a Query or Scan operation:

  • For a Query operation, Condition is used for specifying the KeyConditions to use when querying a table or an index. For KeyConditions, only the following comparison operators are supported:

    EQ | LE | LT | GE | GT | BEGINS_WITH | BETWEEN

    Condition is also used in a QueryFilter, which evaluates the query results and returns only the desired values.

  • For a Scan operation, Condition is used in a ScanFilter, which evaluates the scan results and returns only the desired values.
type scan_input = {
  1. consistent_read : bool option;
    (*

    A Boolean value that determines the read consistency model during the scan:

    • If ConsistentRead is false, then the data returned from Scan might not contain the results from other recently completed write operations (PutItem, UpdateItem, or DeleteItem).
    • If ConsistentRead is true, then all of the write operations that completed before the Scan began are guaranteed to be contained in the Scan response.

    The default setting for ConsistentRead is false.

    The ConsistentRead parameter is not supported on global secondary indexes. If you scan a global secondary index with ConsistentRead set to true, you will receive a ValidationException.

    *)
  2. expression_attribute_values : (string * attribute_value) list option;
    (*

    One or more values that can be substituted in an expression.

    Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the ProductStatus attribute was one of the following:

    Available | Backordered | Discontinued

    You would first need to specify ExpressionAttributeValues as follows:

    { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

    You could then use these values in an expression, such as this:

    ProductStatus IN (:avail, :back, :disc)

    For more information on expression attribute values, see Condition Expressions in the Amazon DynamoDB Developer Guide.

    *)
  3. expression_attribute_names : (string * string) list option;
    (*

    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

    • To access an attribute whose name conflicts with a DynamoDB reserved word.
    • To create a placeholder for repeating occurrences of an attribute name in an expression.
    • To prevent special characters in an attribute name from being misinterpreted in an expression.

    Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

    • Percentile

    The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:

    • {"#P":"Percentile"}

    You could then use this substitution in an expression, as in this example:

    • #P = :val

    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

    For more information on expression attribute names, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

    *)
  4. filter_expression : string option;
    (*

    A string that contains conditions that DynamoDB applies after the Scan operation, but before the data is returned to you. Items that do not satisfy the FilterExpression criteria are not returned.

    A FilterExpression is applied after the items have already been read; the process of filtering does not consume any additional read capacity units.

    For more information, see Filter Expressions in the Amazon DynamoDB Developer Guide.

    *)
  5. projection_expression : string option;
    (*

    A string that identifies one or more attributes to retrieve from the specified table or index. These attributes can include scalars, sets, or elements of a JSON document. The attributes in the expression must be separated by commas.

    If no attribute names are specified, then all attributes will be returned. If any of the requested attributes are not found, they will not appear in the result.

    For more information, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

    *)
  6. segment : int option;
    (*

    For a parallel Scan request, Segment identifies an individual segment to be scanned by an application worker.

    Segment IDs are zero-based, so the first segment is always 0. For example, if you want to use four application threads to scan a table or an index, then the first thread specifies a Segment value of 0, the second thread specifies 1, and so on.

    The value of LastEvaluatedKey returned from a parallel Scan request must be used as ExclusiveStartKey with the same segment ID in a subsequent Scan operation.

    The value for Segment must be greater than or equal to 0, and less than the value provided for TotalSegments.

    If you provide Segment, you must also provide TotalSegments.

    *)
  7. total_segments : int option;
    (*

    For a parallel Scan request, TotalSegments represents the total number of segments into which the Scan operation will be divided. The value of TotalSegments corresponds to the number of application workers that will perform the parallel scan. For example, if you want to use four application threads to scan a table or an index, specify a TotalSegments value of 4.

    The value for TotalSegments must be greater than or equal to 1, and less than or equal to 1000000. If you specify a TotalSegments value of 1, the Scan operation will be sequential rather than parallel.

    If you specify TotalSegments, you must also specify Segment.

  8. return_consumed_capacity : return_consumed_capacity option;
  9. exclusive_start_key : (string * attribute_value) list option;
    (*

    The primary key of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedKey in the previous operation.

    The data type for ExclusiveStartKey must be String, Number or Binary. No set data types are allowed.

    In a parallel scan, a Scan request that includes ExclusiveStartKey must specify the same segment whose previous Scan returned the corresponding value of LastEvaluatedKey.

  12. select : select option;
    (*

    The attributes to be returned in the result. You can retrieve all item attributes, specific item attributes, the count of matching items, or in the case of an index, some or all of the attributes projected into the index.

    • ALL_ATTRIBUTES - Returns all of the item attributes from the specified table or index. If you query a local secondary index, then for each matching item in the index, DynamoDB fetches the entire item from the parent table. If the index is configured to project all item attributes, then all of the data can be obtained from the local secondary index, and no fetching is required.
    • ALL_PROJECTED_ATTRIBUTES - Allowed only when querying an index. Retrieves all attributes that have been projected into the index. If the index is configured to project all attributes, this return value is equivalent to specifying ALL_ATTRIBUTES.
    • COUNT - Returns the number of matching items, rather than the matching items themselves. Note that this uses the same quantity of read capacity units as getting the items, and is subject to the same item size calculations.

    • SPECIFIC_ATTRIBUTES - Returns only the attributes listed in ProjectionExpression. This return value is equivalent to specifying ProjectionExpression without specifying any value for Select.

      If you query or scan a local secondary index and request only attributes that are projected into that index, the operation reads only the index and not the table. If any of the requested attributes are not projected into the local secondary index, DynamoDB fetches each of these attributes from the parent table. This extra fetching incurs additional throughput cost and latency.

      If you query or scan a global secondary index, you can only request attributes that are projected into the index. Global secondary index queries cannot fetch attributes from the parent table.

    If neither Select nor ProjectionExpression are specified, DynamoDB defaults to ALL_ATTRIBUTES when accessing a table, and ALL_PROJECTED_ATTRIBUTES when accessing an index. You cannot use both Select and ProjectionExpression together in a single request, unless the value for Select is SPECIFIC_ATTRIBUTES. (This usage is equivalent to specifying ProjectionExpression without any value for Select.)

    If you use the ProjectionExpression parameter, then the value for Select can only be SPECIFIC_ATTRIBUTES. Any other value for Select will return an error.

    *)
  13. limit : int option;
    (*

    The maximum number of items to evaluate (not necessarily the number of matching items). If DynamoDB processes the number of items up to the limit while processing the results, it stops the operation and returns the matching values up to that point, and a key in LastEvaluatedKey to apply in a subsequent operation, so that you can pick up where you left off. Also, if the processed dataset size exceeds 1 MB before DynamoDB reaches this limit, it stops the operation and returns the matching values up to the limit, and a key in LastEvaluatedKey to apply in a subsequent operation to continue the operation. For more information, see Working with Queries in the Amazon DynamoDB Developer Guide.

    The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from DynamoDB's usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

    The sort key of an item is also known as its range attribute. The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

  3. scanned_count : int option;
    (*

    The number of items evaluated, before any QueryFilter is applied. A high ScannedCount value with few, or no, Count results indicates an inefficient Query operation. For more information, see Count and ScannedCount in the Amazon DynamoDB Developer Guide.

    You would first need to specify ExpressionAttributeValues as follows:

    { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

    You could then use these values in an expression, such as this:

    ProductStatus IN (:avail, :back, :disc)

    For more information on expression attribute values, see Specifying Conditions in the Amazon DynamoDB Developer Guide.

    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

    For more information on expression attribute names, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

    *)
  3. key_condition_expression : string option;
    (*

    The condition that specifies the key values for items to be retrieved by the Query action.

    The condition must perform an equality test on a single partition key value.

    The condition can optionally perform one of several comparison tests on a single sort key value. This allows Query to retrieve one item with a given partition key value and sort key value, or several items that have the same partition key value but different sort key values.

    The partition key equality test is required, and must be specified in the following format:

    partitionKeyName = :partitionkeyval

    If you also want to provide a condition for the sort key, it must be combined using AND with the condition for the sort key. Following is an example, using the = comparison operator for the sort key:

    partitionKeyName = :partitionkeyval AND sortKeyName = :sortkeyval

    Valid comparisons for the sort key condition are as follows:

    • sortKeyName = :sortkeyval - true if the sort key value is equal to :sortkeyval.
    • sortKeyName < :sortkeyval - true if the sort key value is less than :sortkeyval.
    • sortKeyName <= :sortkeyval - true if the sort key value is less than or equal to :sortkeyval.
    • sortKeyName > :sortkeyval - true if the sort key value is greater than :sortkeyval.
    • sortKeyName >= :sortkeyval - true if the sort key value is greater than or equal to :sortkeyval.
    • sortKeyName BETWEEN :sortkeyval1 AND :sortkeyval2 - true if the sort key value is greater than or equal to :sortkeyval1, and less than or equal to :sortkeyval2.
    • begins_with ( sortKeyName, :sortkeyval ) - true if the sort key value begins with a particular operand. (You cannot use this function with a sort key that is of type Number.) Note that the function name begins_with is case-sensitive.

    Use the ExpressionAttributeValues parameter to replace tokens such as :partitionval and :sortval with actual values at runtime.

    You can optionally use the ExpressionAttributeNames parameter to replace the names of the partition key and sort key with placeholder tokens. This option might be necessary if an attribute name conflicts with a DynamoDB reserved word. For example, the following KeyConditionExpression parameter causes an error because Size is a reserved word:

    • Size = :myval

    To work around this, define a placeholder (such a #S) to represent the attribute name Size. KeyConditionExpression then is as follows:

    • #S = :myval

    Specifies the order for index traversal: If true (default), the traversal is performed in ascending order; if false, the traversal is performed in descending order.

    Items with the same partition key value are stored in sorted order by sort key. If the sort key data type is Number, the results are stored in numeric order. For type String, the results are stored in order of UTF-8 bytes. For type Binary, DynamoDB treats each byte of the binary data as unsigned.

    If ScanIndexForward is true, DynamoDB returns the results in the order in which they are stored (by sort key value). This is the default behavior. If ScanIndexForward is false, DynamoDB reads the results in reverse order by sort key value, and then returns the results to the client.

    (*

    Set this parameter to true to confirm that you want to remove your permissions to change the policy of this resource in the future.

    *)
  2. expected_revision_id : string option;
    (*

    A string value that you can use to conditionally update your policy. You can provide the revision ID of your existing policy to make mutating requests against that policy.

    When you provide an expected revision ID, if the revision ID of the existing policy on the resource doesn't match or if there's no policy attached to the resource, your request will be rejected with a PolicyNotFoundException.

    To conditionally attach a policy when no policy exists for the resource, specify NO_POLICY for the revision ID.

    *)
  3. policy : string;
    (*

    An Amazon Web Services resource-based policy document in JSON format.

    • The maximum size supported for a resource-based policy document is 20 KB. DynamoDB counts whitespaces when calculating the size of a policy against this limit.
    • Within a resource-based policy, if the action for a DynamoDB service-linked role (SLR) to replicate data for a global table is denied, adding or deleting a replica will fail with an error.

    For a full list of all considerations that apply while attaching a resource-based policy, see Resource-based policy considerations.

    *)
  4. resource_arn : string;
    (*

    The Amazon Resource Name (ARN) of the DynamoDB resource to which the policy will be attached. The resources you can specify include tables and streams.

    You can control index permissions using the base table's policy. To specify the same permission level for your table and its indexes, you can provide both the table and index Amazon Resource Name (ARN)s in the Resource field of a given Statement in your policy document. Alternatively, to specify different permissions for your table, indexes, or both, you can define multiple Statement fields in your policy document.

    *)
}
type policy_not_found_exception = {
  1. message : string option;
}

The operation tried to access a nonexistent resource-based policy.

If you specified an ExpectedRevisionId, it's possible that a policy is present for the resource but its revision ID didn't match the expected value.

type put_item_output = {
  1. item_collection_metrics : item_collection_metrics option;
    (*

    Information about item collections, if any, that were affected by the PutItem operation. ItemCollectionMetrics is only returned if the ReturnItemCollectionMetrics parameter was specified. If the table does not have any local secondary indexes, this information is not returned in the response.

    Each ItemCollectionMetrics element consists of:

    • ItemCollectionKey - The partition key value of the item collection. This is the same as the partition key value of the item itself.

    • SizeEstimateRangeGB - An estimate of item collection size, in gigabytes. This value is a two-element array containing a lower bound and an upper bound for the estimate. The estimate includes the size of all the items in the table, plus the size of all attributes projected into all of the local secondary indexes on that table. Use this estimate to measure whether a local secondary index is approaching its size limit.

      The estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.

    *)
  2. consumed_capacity : consumed_capacity option;
    (*

    The capacity units consumed by the PutItem operation. The data returned includes the total provisioned throughput consumed, along with statistics for the table and any indexes involved in the operation. ConsumedCapacity is only returned if the ReturnConsumedCapacity parameter was specified. For more information, see Capacity unity consumption for write operations in the Amazon DynamoDB Developer Guide.

    *)
  3. attributes : (string * attribute_value) list option;
    (*

    The attribute values as they appeared before the PutItem operation, but only if ReturnValues is specified as ALL_OLD in the request. Each element consists of an attribute name and an attribute value.

    *)
}

Represents the output of a PutItem operation.

type put_item_input = {
  1. return_values_on_condition_check_failure : return_values_on_condition_check_failure option;
    (*

    An optional parameter that returns the item attributes for a PutItem operation that failed a condition check.

    There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

    *)
  2. expression_attribute_values : (string * attribute_value) list option;
    (*

    One or more values that can be substituted in an expression.

    Use the : (colon) character in an expression to dereference an attribute value. For example, suppose that you wanted to check whether the value of the ProductStatus attribute was one of the following:

    Available | Backordered | Discontinued

    You would first need to specify ExpressionAttributeValues as follows:

    { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

    You could then use these values in an expression, such as this:

    ProductStatus IN (:avail, :back, :disc)

    For more information on expression attribute values, see Condition Expressions in the Amazon DynamoDB Developer Guide.

    *)
  3. expression_attribute_names : (string * string) list option;
    (*

    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

    • To access an attribute whose name conflicts with a DynamoDB reserved word.
    • To create a placeholder for repeating occurrences of an attribute name in an expression.
    • To prevent special characters in an attribute name from being misinterpreted in an expression.

    Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

    • Percentile

    The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:

    • {"#P":"Percentile"}

    You could then use this substitution in an expression, as in this example:

    • #P = :val

    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

    For more information on expression attribute names, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

    *)
  4. condition_expression : string option;
    (*

    A condition that must be satisfied in order for a conditional PutItem operation to succeed.

    An expression can contain any of the following:

    • Functions: attribute_exists | attribute_not_exists | attribute_type | contains | begins_with | size

      These function names are case-sensitive.

    • Comparison operators: = | <> | < | > | <= | >= | BETWEEN | IN
    • Logical operators: AND | OR | NOT

    For more information on condition expressions, see Condition Expressions in the Amazon DynamoDB Developer Guide.

    *)
  5. conditional_operator : conditional_operator option;
    (*

    This is a legacy parameter. Use ConditionExpression instead. For more information, see ConditionalOperator in the Amazon DynamoDB Developer Guide.

    *)
  6. return_item_collection_metrics : return_item_collection_metrics option;
    (*

    Determines whether item collection metrics are returned. If set to SIZE, the response includes statistics about item collections, if any, that were modified during the operation are returned in the response. If set to NONE (the default), no statistics are returned.

    *)
  7. return_consumed_capacity : return_consumed_capacity option;
  8. return_values : return_value option;
    (*

    Use ReturnValues if you want to get the item attributes as they appeared before they were updated with the PutItem request. For PutItem, the valid values are:

    • NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)
    • ALL_OLD - If PutItem overwrote an attribute name-value pair, then the content of the old item is returned.

    The values returned are strongly consistent.

    There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

    The ReturnValues parameter is used by several DynamoDB operations; however, PutItem does not recognize any values other than NONE or ALL_OLD.

    *)
  9. expected : (string * expected_attribute_value) list option;
    (*

    This is a legacy parameter. Use ConditionExpression instead. For more information, see Expected in the Amazon DynamoDB Developer Guide.

    *)
  10. item : (string * attribute_value) list;
    (*

    A map of attribute name/value pairs, one for each attribute. Only the primary key attributes are required; you can optionally provide other attribute name-value pairs for the item.

    You must provide all of the attributes for the primary key. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide both values for both the partition key and the sort key.

    If you specify any attributes that are part of an index key, then the data types for those attributes must match those of the schema in the table's attribute definition.

    Empty String and Binary attribute values are allowed. Attribute values of type String and Binary must have a length greater than zero if the attribute is used as a key attribute for a table or index.

    For more information about primary keys, see Primary Key in the Amazon DynamoDB Developer Guide.

    Each element in the Item map is an AttributeValue object.

    *)

    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

    • To access an attribute whose name conflicts with a DynamoDB reserved word.
    • To create a placeholder for repeating occurrences of an attribute name in an expression.
    • To prevent special characters in an attribute name from being misinterpreted in an expression.

    Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

    • Percentile

    The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:

    • {"#P":"Percentile"}

    You could then use this substitution in an expression, as in this example:

    • #P = :val

    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

    You would first need to specify ExpressionAttributeValues as follows:

    { ":avail":{"S":"Available"}, ":back":{"S":"Backordered"}, ":disc":{"S":"Discontinued"} }

    You could then use these values in an expression, such as this:

    ProductStatus IN (:avail, :back, :disc)

    *)
  3. expression_attribute_names : (string * string) list option;
    (*

    One or more substitution tokens for attribute names in an expression. The following are some use cases for using ExpressionAttributeNames:

    • To access an attribute whose name conflicts with a DynamoDB reserved word.
    • To create a placeholder for repeating occurrences of an attribute name in an expression.
    • To prevent special characters in an attribute name from being misinterpreted in an expression.

    Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

    • Percentile

    The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:

    • {"#P":"Percentile"}

    You could then use this substitution in an expression, as in this example:

    • #P = :val

    Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

    For more information on expression attribute names, see Specifying Item Attributes in the Amazon DynamoDB Developer Guide.

    • NONE - If ReturnValues is not specified, or if its value is NONE, then nothing is returned. (This setting is the default for ReturnValues.)
    • ALL_OLD - The content of the old item is returned.

    There is no additional cost associated with requesting a return value aside from the small network and processing overhead of receiving a larger response. No read capacity units are consumed.

    The ReturnValues parameter is used by several DynamoDB operations; however, DeleteItem does not recognize any values other than NONE or ALL_OLD.

    Specifies the attributes that make up the primary key for a table or an index. The attributes in KeySchema must also be defined in the AttributeDefinitions array. For more information, see Data Model in the Amazon DynamoDB Developer Guide.

    Each KeySchemaElement in the array is composed of:

    • AttributeName - The name of this key attribute.

    • KeyType - The role that the key attribute will assume:

      • HASH - partition key
      • RANGE - sort key

    The partition key of an item is also known as its hash attribute. The term "hash attribute" derives from the DynamoDB usage of an internal hash function to evenly distribute data items across partitions, based on their partition key values.

    The sort key of an item is also known as its range attribute. The term "range attribute" derives from the way DynamoDB stores items with the same partition key physically close together, in sorted order by the sort key value.

    For a simple primary key (partition key), you must provide exactly one element with a KeyType of HASH.

    For a composite primary key (partition key and sort key), you must provide exactly two elements, in this order: The first element must have a KeyType of HASH, and the second element must have a KeyType of RANGE.

    *)
  2. return_consumed_capacity : return_consumed_capacity option;
  3. request_items : (string * write_request list) list;
    (*

    A map of one or more table names or table ARNs and, for each table, a list of operations to be performed (DeleteRequest or PutRequest). Each element in the map consists of the following:

    • DeleteRequest - Perform a DeleteItem operation on the specified item. The item to be deleted is identified by a Key subelement:

      • Key - A map of primary key attribute values that uniquely identify the item. Each entry in this map consists of an attribute name and an attribute value. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.

    • PutRequest - Perform a PutItem operation on the specified item. The item to be put is identified by an Item subelement:

      • Item - A map of attributes and their values. Each entry in this map consists of an attribute name and an attribute value. Attribute values must not be null; string and binary type attributes must have lengths greater than zero; and set type attributes must not be empty. Requests that contain empty values are rejected with a ValidationException exception.

        If you specify any attributes that are part of an index key, then the data types for those attributes must match those of the schema in the table's attribute definition.

    *)

Represents the input of a BatchWriteItem operation.

type batch_get_item_output = {
  1. consumed_capacity : consumed_capacity list option;
    (*

    The read capacity units consumed by the entire BatchGetItem operation.

    Each element consists of:

    • TableName - The table that consumed the provisioned throughput.
    • CapacityUnits - The total number of capacity units consumed.
    *)
  2. unprocessed_keys : (string * keys_and_attributes) list option;
    (*

    A map of tables and their respective keys that were not processed with the current response. The UnprocessedKeys value is in the same form as RequestItems, so the value can be provided directly to a subsequent BatchGetItem operation. For more information, see RequestItems in the Request Parameters section.

    Each element consists of:

    • Keys - An array of primary key attribute values that define specific items in the table.
    • ProjectionExpression - One or more attributes to be retrieved from the table or index. By default, all attributes are returned. If a requested attribute is not found, it does not appear in the result.
    • ConsistentRead - The consistency of a read operation. If set to true, then a strongly consistent read is used; otherwise, an eventually consistent read is used.

    If there are no unprocessed keys remaining, the response contains an empty UnprocessedKeys map.

    *)
  3. responses : (string * (string * attribute_value) list list) list option;
    (*

    A map of table name or table ARN to a list of items. Each object in Responses consists of a table name or ARN, along with a map of attribute data consisting of the data type and attribute value.

    *)
}

Represents the output of a BatchGetItem operation.

type batch_get_item_input = {
  1. return_consumed_capacity : return_consumed_capacity option;
  2. request_items : (string * keys_and_attributes) list;
    (*

    A map of one or more table names or table ARNs and, for each table, a map that describes one or more items to retrieve from that table. Each table name or ARN can be used only once per BatchGetItem request.

    Each element in the map of items to retrieve consists of the following:

    • ConsistentRead - If true, a strongly consistent read is used; if false (the default), an eventually consistent read is used.

    • ExpressionAttributeNames - One or more substitution tokens for attribute names in the ProjectionExpression parameter. The following are some use cases for using ExpressionAttributeNames:

      • To access an attribute whose name conflicts with a DynamoDB reserved word.
      • To create a placeholder for repeating occurrences of an attribute name in an expression.
      • To prevent special characters in an attribute name from being misinterpreted in an expression.

      Use the # character in an expression to dereference an attribute name. For example, consider the following attribute name:

      • Percentile

      The name of this attribute conflicts with a reserved word, so it cannot be used directly in an expression. (For the complete list of reserved words, see Reserved Words in the Amazon DynamoDB Developer Guide). To work around this, you could specify the following for ExpressionAttributeNames:

      • {"#P":"Percentile"}

      You could then use this substitution in an expression, as in this example:

      • #P = :val

      Tokens that begin with the : character are expression attribute values, which are placeholders for the actual value at runtime.

      For more information about expression attribute names, see Accessing Item Attributes in the Amazon DynamoDB Developer Guide.

    • Keys - An array of primary key attribute values that define specific items in the table. For each primary key, you must provide all of the key attributes. For example, with a simple primary key, you only need to provide the partition key value. For a composite key, you must provide both the partition key value and the sort key value.

    • ProjectionExpression - A string that identifies one or more attributes to retrieve from the table. These attributes can include scalars, sets, or elements of a JSON document. The attributes in the expression must be separated by commas.

      If no attribute names are specified, then all attributes are returned. If any of the requested attributes are not found, they do not appear in the result.

      For more information, see Accessing Item Attributes in the Amazon DynamoDB Developer Guide.

    • AttributesToGet - This is a legacy parameter. Use ProjectionExpression instead. For more information, see AttributesToGet in the Amazon DynamoDB Developer Guide.

Amazon DynamoDB Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. DynamoDB lets you offload the administrative burdens of operating and scaling a distributed database, so that you don't have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaling.

With DynamoDB, you can create database tables that can store and retrieve any amount of data, and serve any level of request traffic. You can scale up or scale down your tables' throughput capacity without downtime or performance degradation, and use the Amazon Web Services Management Console to monitor resource utilization and performance metrics.

DynamoDB automatically spreads the data and traffic for your tables over a sufficient number of servers to handle your throughput and storage requirements, while maintaining consistent and fast performance. All of your data is stored on solid state disks (SSDs) and automatically replicated across multiple Availability Zones in an Amazon Web Services Region, providing built-in high availability and data durability.
