It doesn't write to the same object. The application thread `FetchBuffer` is created in `PrototypeAsyncConsumer` and the background thread `FetchBuffer` is created in `AbstractFetch`. For point #2, I think your [other comment](https://github.com/apache/kafka/pull/14406#discussion_r1342984775) is correct. I'm not yet sure how to maintain those two fetch buffers separately without running into that race condition. -- This is an automated message from the Apache Git Service.
