      Description

      Implement optimized support for collations other than latin1/utf8[mb4] in MyRocks with Percona Server 8.0.

      This is an efficiency improvement to allow MyRocks to reconstruct and return key data directly from an index read (covering index read and ICP) rather than needing to perform a primary key lookup after an index lookup. This will be achieved by storing the original key data in the keys ‘value’ area.

      This will require an index version bump to maintain backwards compatibility with data previously stored in Percona Server 8.0.
