  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.

  <p>
  The estimate is subject to change over time; therefore, do not rely on the precision or accuracy of the estimate.
