class Aws::DynamoDB::Types::UpdateItemOutput

Represents the output of an `UpdateItem` operation.

@!attribute [rw] attributes

A map of attribute values as they appear before or after the
`UpdateItem` operation, as determined by the `ReturnValues`
parameter.

The `Attributes` map is only present if `ReturnValues` was specified
as something other than `NONE` in the request. Each element
represents one attribute.
@return [Hash<String,Types::AttributeValue>]

@!attribute [rw] consumed_capacity

The capacity units consumed by the `UpdateItem` 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 [Provisioned Throughput][1] in the *Amazon DynamoDB
Developer Guide*.

@return [Types::ConsumedCapacity]

@!attribute [rw] item_collection_metrics

Information about item collections, if any, that were affected by
the `UpdateItem` 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.
@return [Types::ItemCollectionMetrics]
