Boaz Ben-Zvi commented on DRILL-6027:
-------------------------------------
The code changes up to now are at:
[https://github.com/apache/drill/compare/master...Ben-Zvi:HashJoinSpill]
The work includes splitting the Hash-Join work into partitions (both Build and
Probe sides), and replacing the generated code for moving rows around with the
new appendRow() calls.
All the user regressions are now passing.
