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