Work Description: KevinGG commented on pull request #11174: [BEAM-7923]
Pop failed transform in CombineGlobally
URL: https://github.com/apache/beam/pull/11174
1. The problem: when the CombineGlobally raises the ValueError, it
breaks out the process of transform `apply` where the current transform
has been pushed into a transform stack, to be expanded and then popped out
in the end.
Without the popping out, the pipeline will hold a current transform that
is referring the failed CombineGlobally transform and never changes,
meaning the pipeline will not accept any new transforms after.
2. It did not affect non-interactive usages because when the pipeline
construction runs into an error, the user has to restart the whole
program and nothing has been executed at the point the error is raised,
so no side-effects.
3. It did leave the pipeline in a dead state when the user constructs
pipelines in an interactive environment.
4. The pop before raising the error allows the transform stack to
recover from the failed state.
