frankvicky opened a new pull request, #17946: URL: https://github.com/apache/kafka/pull/17946
JIRA: KAFKA-10790 As we already know, the `callback` of `Producer#send` is executed by the `ioThread`. Due to this design, many application bugs have been caused by calling `Producer#flush` in callback，which leads to deadlocks. This PR aims to add protection against such scenarios. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
