> Sort incorrectly limits batch size to 65535 records rather than 65536

> Key: DRILL-6080
> URL: https://issues.apache.org/jira/browse/DRILL-6080
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.12.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Minor
> Labels: ready-to-commit
> Fix For: 1.13.0
>
>
> 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`.
