Service: Amazon DynamoDB
Information about item collections, if any, that were affected by the operation.
ItemCollectionMetrics is only returned if the request asked for it. If the
table does not have any local secondary indexes, this information is not returned in the response.
In the following list, the required parameters are described first.

Type: String to AttributeValue object map
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.
Type: array of Doubles
