Function updateChildById

updateChildById<DocumentType>(context, collectionName, objectId, parentObjectId, updates, options?): Promise<DocumentType>
Update a child document using its _id and parent _id.

This operation allows you to do a partial update of a collection document i.e. without specifying all the values (it uses DynamoDBs UpdateItem` operation).

At this time, the updates value just updates specified key paths on the target document.

If some of the update key paths are indexed values, the indexes will also be updated. Because of this, you must specify all the key values in an access pattern to ensure indexes are updated consistently.
