Ideally, we should wait for all tasks after rescale to become running. That's exactly what FLINK-34336 fix. > Why does it increase the hang possibility? When the rescale with cooldown=30s, the rescale action will be executed after 30s. When the `waitForRunningTasks` is called, the job is still running with old parallelism, so the `waitForRunningTasks` can be done. When we disable the scaling cooldown, the rescale may happen immediately. When it happens, the job will be running with `2 * parallelism2`, so `waitForRunningTasks` with old parallelism2 will be hang forever. > And why did we merge it into master? IIUC, we should wait for all tasks after rescale to become running. But these 2 callers wait for all tasks before rescale. These 2 wait are unexpected, so I think it's a separate bug regardless of we disable/enable cooldown. It means we should wait for all tasks after rescale even if we enable cooldown=30s. That's why I create a separate JIRA (FLINK-34336) to follow it. Why do I merge it into master? 1. I think `Disable the scaling cooldown to speed up the test` and FLINK-34336 are separate 2. I guess `Disable the scaling cooldown to speed up the test` may be cause AutoRescalingITCase hang, so I prepare https://github.com/apache/flink/pull/24248 in advanced. It's easy to be merged to fix the hang. > Why do we merge it then now? 1. `Disable the scaling cooldown to speed up the test` is a minor improvement for test instead of bugfix. So it's not necessary for 1.19 IIUC. 2. 1.19 will be released soon, I'm afraid to affect this release. So I merge it in master(1.20) first. 3. After FLINK-34226 is fixed, this minor improvement doesn't have any negative impact(I didn't notice any), so merging it may be make sense.

If you accept that you're filling in the information one \"with\" method at a time, you're going to temporary have fields which are null until all information is provided. Your analysis is correct, but I think we should reconsider the assumption that we must only provide `with` methods as the public API. As far as I can tell, there are three things `with` methods accomplish here: 1. null checks 2. helper methods for StaticValueProviders 3. create a modified copy of a configuration Item 1 is best left to the AutoValue generated code, and 2 is unneeded if we get remove ValueProviders. 3 is the only one that really provides value IMO.
