Julian Hyde updated CALCITE-4759:
---------------------------------
Description:
JoinPushThroughJoinRule doesn't ever get to the onMatch() condition, even when
presented with a plan with two back to back joins. I found this as a test
failure while upgrading Beam from Calcite 1.20 to 1.25.
Looks like this was introduced by [PR
2024|https://github.com/apache/calcite/pull/2024] (CALCITE-3923), I was able to
workaround the issue by patching in the match rule prior to this change: commit
[6c5c04, 'Workaround CALCITE-4759 in
JoinPushThroughJoinRule'|https://github.com/apache/beam/pull/14729/commits/6c5c04b8fc903fc0130ca06d4d8f2dbd082a3341]
