tvalentyn opened a new issue, #26209: URL: https://github.com/apache/beam/issues/26209
### What happened? Combiner combiner lifting and combiner `with_fanout` utility copy portions of Beam's subgraph related to combiners. It appears that unpickling cloudpickle-pickled bytes encoding those subgraph results in multiple CombineFns sharing the same state, which results in side-effect in combiner setup and teardown initialization. TODO: add details, failure examples and code pointers. ### Issue Priority Priority: 2 (default / most bugs should be filed as P2) ### Issue Components - [X] Component: Python SDK - [ ] Component: Java SDK - [ ] Component: Go SDK - [ ] Component: Typescript SDK - [ ] Component: IO connector - [ ] Component: Beam examples - [ ] Component: Beam playground - [ ] Component: Beam katas - [ ] Component: Website - [ ] Component: Spark Runner - [ ] Component: Flink Runner - [ ] Component: Samza Runner - [ ] Component: Twister2 Runner - [ ] Component: Hazelcast Jet Runner - [ ] Component: Google Cloud Dataflow Runner -- This is an automated message from the Apache Git Service.
