---------------------------------------
Summary: JoinPushThroughJoinRule does not match two joins
Key: CALCITE-4759
URL: https://issues.apache.org/jira/browse/CALCITE-4759
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.25.0
Reporter: Andrew Pilloud
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 https://github.com/apache/calcite/pull/2024,
I was able to workaround the issue by patching in the match rule prior to this
change:
