It seems that fetchOffsetMetadata() needs to take in nextFetchOffset too. This way, if the offset matches, we can avoid the readFromLog call. 2. We want to be a bit careful with the offset matching. In the common case, the nextFetchOffset is always aligned on batch boundary so it will match fetchOffsetMetadata.messageOffset. However, a user could initialize an arbitrary offset in the middle of a batch. In this case, nextFetchOffset won't match fetchOffsetMetadata.messageOffset since the latter is at the batch boundary. So, we need to understand the impact of that. -- This is an automated message from the Apache Git Service.
