----------------------------------------
I don't think we're moving to RcoskDB 9 in Ozone 2.0 so moving it out.
> Add a layout feature before upgrading to RocksDB 9.x

> Key: HDDS-10555
> URL: https://issues.apache.org/jira/browse/HDDS-10555
> Project: Apache Ozone
> Issue Type: Task
> Affects Versions: 1.4.0
> Reporter: Ethan Rose
> Priority: Blocker
>
> RocksDB 9.0 contains the following in its [release
> notes|https://github.com/facebook/rocksdb/releases/tag/v9.0.0]:
> {quote}format_version=6 is the new default setting in BlockBasedTableOptions,
> for more robust data integrity checking. DBs and SST files written with this
> setting cannot be read by RocksDB versions before 8.6.0.
> {quote}
> Since we are at {{7.7.3}} , we will need to add a layout feature that sets
> {{format_version}} < 6 until finalize to ensure that downgrades work before
> finalization. We are not ready to upgrade yet, but for now I'm just filing
> this Jira as a note for when we eventually cross into the 9.x major version
> series.
> Ideally our upgrade/downgrade testing would catch this issue as well.
