[jira] [Created] (KAFKA-13896) Support unsafe downgrades in KRaft

David Arthur created KAFKA-13896:
------------------------------------

             Summary: Support unsafe downgrades in KRaft
                 Key: KAFKA-13896
                 URL: https://issues.apache.org/jira/browse/KAFKA-13896
             Project: Kafka
          Issue Type: Sub-task
          Components: controller, kraft
            Reporter: David Arthur


In order to support the "unsafe" downgrade specified in KIP-778 we need to be able to generate a downgraded snapshot on the broker and controller. This snapshot will write out metadata records at the record level that matches the target metadata.version. Records that were added after the target metadata.version will be omitted from the snapshot.

This also means we need a way to correlate record versions with metadata.version.
