----------------------------------
Summary: Perform CRC validation on KRaft Batch Records and
Snapshots
Key: KAFKA-14104
URL: https://issues.apache.org/jira/browse/KAFKA-14104
Project: Kafka
Issue Type: Bug
Affects Versions: 3.2.0
Reporter: Niket Goel
Fix For: 3.3
Today we stamp the BatchRecord header with a CRC [1] and verify that CRC before
the log is written to disk [2]. The CRC checks should also be verified when the
records are read back from disk. The same procedure should be followed for
KRaft snapshots as well.
