Ismael Juma cf7029c026 KAFKA-13093: Log compaction should write new segments with record version v2 (KIP-724) (#18321) ... Convert v0/v1 record batches to v2 during compaction even if said record batches would be written with no change otherwise. A few important details: 1. V0 compressed record batch with multiple records is converted into single V2 record batch 2. V0 uncompressed records are converted into single record V2 record batches 3. V0 records are converted to V2 records with timestampType set to `CreateTime` and the timestamp is `-1`. 4. The `KAFKA-4298` workaround is no longer needed since the conversion to V2 fixes the issue too. 5. Removed a log warning applicable to consumers older than 0.10.1 - they are no longer supported. 6. Added back the ability to append records with v0/v1 (for testing only). 7. The creation of the leader epoch cache is no longer optional since the record version config is effectively always V2. Add integration tests, these tests existed before #18267 - restored, modified and extended them. Reviewers: Jun Rao <jun@confluent.io>		2025-01-09 09:37:23 -08:00
