["txomon (via GitHub)" <gi...@apache.org>]

txomon opened a new issue, #25442:
URL: https://github.com/apache/beam/issues/25442

   ### 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.
