We optimize consumed read capacity by limiting the queries to read at most page size entries per underlying dynamodb request. (Multiple requests might be necessary to fill page full of data)
This should significantly reduce the consumed read capacity in cases where the persistence service is queried with page size, as the default before was to read up to 1MB of data. For example, with historicState, the page size is set to 1, and only the first page is of interest.
