> As titled, in current {{RocksDBKeyedStateBackend}} we use {{keySerializer}}
> rather than {{keySerializerProvider.currentSchemaSerializer()}}, which is
> incorrect. The issue is not revealed in existing UT since current cases
> didn't check snapshot after state schema migration.
> This is a regression issue caused by the FLINK-10043 refactoring work.
