Hi, dear community and release managers,
Thanks for bringing this up. When testing the release candidate #0 for the batch scenario, I found an issue of frequent flushing in Hybrid shuffle. It is a new bug introduced by 1.18 and may significantly impact the performance of shuffle writing. The fix ticket FLINK-33044[1] has been reviewed and approved. To prevent any performance issues, I would like to backport the fix to version 1.18 unless there are any objections. Glad to hear your suggestions.
