   @caipengbo PR #1534 has been pending for a while. This feature is quite useful since it can help the cluster migration avoid depending on the log data of the write batch except for the performance benefit. I'm very eager to see this feature done, but #1535 has too many conflicts
   and it's a bit hard to review for now.
   
   So I'm not sure if you're willing to continue working on this feature. If yes, I think we can
   break down this feature into a few PRs and add more tests like:
   
   - [ ] Add the `ApplyBatch` command
   - [ ] Implement the merge iterator for iterating SST keys
   - [ ] Implement WAL iterator for migrating by WAL logs
   - [ ] Implement the migration by applying raw batch
   - [ ] Make the raw batch migration parameters configurable
