---------------------------------
Summary: 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
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.
