Main assumption here is that if is_big is good enough for
GetBatchItems operation it should work well also for Scan,
Query and GetRecords. And it's easier to maintain more unified
code.
Additionally 'future<> print' documentation used for streaming
suggests that there is quite big overhead so since it seems the
only motivation for streaming was to reduce contiguous allocation
size below some threshold we should not stream when this threshold
is not exceeded.
