[GitHub] [beam] robinyqiu opened a new pull request #12112: Avoid unnecessary window configuration for GlobalWindows in BeamCoGBKJoinRel
robinyqiu opened a new pull request #12112:
URL: https://github.com/apache/beam/pull/12112
To ensure correctness, https://github.com/apache/beam/pull/7115 added the `Window.configure()` step to set timestamp combiner. This change has caused performance regression for some CalciteSQL pipelines. To restrict the impact, this PR makes sure the `Window.configure()` step is not applied when it is not necessary.

Ah the `StreamingSQLTest.testZetaSQLNestedQueryFour` failed because nothing was emitted from that test pipeline, which doesn't look right.

Ah, this change seems to be breaking `StreamingSQLTest.testZetaSQLNestedQueryFour`.
