There's a potential problem related to #24926 which could manifest in partition consumers to get stuck. The description in #24926 is mostly written by BrokkAI. There are some details missing. One of the problem assumptions I have is that it's possible to have a scenario where there's a race condition between the writability check in dispatchers between the first check and a later check. In this scenario, it's possible that no entries are dispatched and there's no retry that calls `readMoreEntries` later when one of the consumers is writable. This scenario is possible when there's a backlog and no entries are being produced. The consumption would resume after more entries are being produced to the particular topic partition. -- This is an automated message from the Apache Git Service.
