      Description

      Recovery from savepoint already works:

      • changelog off -> on: FLINK-23278
      • changelog on -> off: directly calling underlyingBackend.savepoint() (instead of writer.persist()

      For checkpoints, changelog on -> off doesn't work. Regular state backend will receive materialized and non-aterialized state on recovery. To support it, state changes have to be applied on recovery even if changelog backend is disabled.
