I cannot actually re-produce the failure locally, but by looking at the code I think there's an issue in `produceKeyValuesSynchronously`: when Eos is not enabled, we then need to call `flush` to make sure all records are indeed sent "synchronously". If Eos is enabled the `commitTxn` would flush the records already. ### 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.
