### What happened? #16126 Made an undocumented change when upgrading the pubsub library by adding a 30 second timeout. https://github.com/apache/beam/commit/acff5d1f29246c44513dbe2fe3da53567448bc14#diff-01a2c3bce792ce6a31018973e914a42b7150d06dc9c490a4640148e06ffdfa01R690 This timeout makes streaming pipeline windows with many subscriptions to listen to lag 30*(number of subscriptions) seconds when not all topics are generating messages, causing a minute long window in my case to be emitted after 30 minutes if it has a few messages, or an hour depending on the luck of the scheduler. ### 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.
