Vladimir Sitnikov commented on CALCITE-2223:
--------------------------------------------
[~vvysotskyi], I've tried to apply Calcite 1.18-drill +
https://github.com/apache/calcite/pull/1019 to Drill.
Drill changes are here:
https://github.com/vlsi/drill/compare/956d7a3db6ef4508e0fbcbc590782c927beb8322..CALCITE-pull1019
The result is as follows:

It looks like it is not that bad, and it seems to heal infinite planning issues
as well. Any thoughts regarding pull/1019 and relevant Drill changes?
