> Drill places an upper limit on the number of rows in a batch of 64K. That is 65,536 decimal. When we index records, the indexes run from 0 to 64K-1 or 0 to 65,535.
> The sort code incorrectly uses {{Character.MAX_VALUE}} as the maximum row count. So, if an incoming batch uses the full 64K size, sort ends up splitting batches unnecessarily.
> The fix is to instead use the correct constant `ValueVector.MAX_ROW_COUNT`.
