> When TTL is set on RocksDB, the default usage of log compacted topic for
> changelog isn't appropriate. Ideally, it should match the behavior with a TTL.
> So we would adjust changelog topic setting, when
> 1) TTL is set for RocksDB and
> 2) Changelog is enabled
> 3) User has not set them
> And we would
> 1) Disable log compaction on Kafka changelog topic
> 2) Set topic TTL to be slightly larger than RocksDB TTL
> User should be able to override this behavior through
> TableDescriptor.withConfig(), e.g.
