-------------------------------
Summary: OffsetCommitRequest should have read-after-write logic
Key: KAFKA-6285
URL: https://issues.apache.org/jira/browse/KAFKA-6285
Project: Kafka
Issue Type: Bug
Reporter: Dong Lin
Assignee: Dong Lin
Currently OffsetCommitRequest does not have read-after-write logic and a
consumer can possibly read an older offset value after successfully committing
the offset. This is because broker may respond to OffsetCommitRequest before
writing offset to the disk and the memory.
This is probably not a problem for most users who do not immediately read
offset after committing offset. But it can be a problem if broker fails before
writing offset to disk. It will be nice if we can have read-after-write logic
for OffsetCommitRequest.
