> 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.
