-------------------------------
Summary: Buffer released too early in MemoryPool
Key: KAFKA-20003
URL: https://issues.apache.org/jira/browse/KAFKA-20003
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 4.1.1, 4.0.1, 3.9.1, 3.8.1, 3.7.2, 3.6.2, 3.5.2, 3.4.1,
3.3.2, 3.3.0, 3.2.3, 3.1.2, 3.0.2, 2.8.2, 2.7.2
Reporter: Jun Rao
Fix For: 4.2.0
https://issues.apache.org/jira/browse/KAFKA-10386 we introduced
Type.COMPACT_RECORDS in SchemaGenerator. However, we forgot to add
Type.COMPACT_RECORDS to ApiKeys.retainsBufferReference(). This can cause the
buffer in MemoryPool to be released too early, leading the data corruption and
potential other weird problems.
This issue is already fixed via
https://issues.apache.org/jira/browse/KAFKA-19634, but the changes are large.
We probably should just fix the issue in ApiKeys.retainsBufferReference() in
4.2.0 and earlier versions.
