ProtectedOptionalbatchOptionalReturnDetermines the level of detail about either provisioned or on-demand throughput consumption that is returned in the response:
INDEXES - The response includes the aggregate
ConsumedCapacity for the operation, together with
ConsumedCapacity for each table and secondary index that was
accessed.
Note that some operations, such as GetItem and
BatchGetItem, do not access any indexes at all. In these cases,
specifying INDEXES will only return ConsumedCapacity
information for table(s).
TOTAL - The response includes only the aggregate
ConsumedCapacity for the operation.
NONE - No ConsumedCapacity details are included in the
response.
OptionalReturnDetermines 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.
