Review comment:
Yes, that will be difficult. The only way to do is that is to write a custom
Iterator handler for RocksDB which we have done in
org.apache.hadoop.ozone.recon.tasks.OMDBUpdatesHandler. The tests in
org.apache.hadoop.ozone.recon.tasks.TestOMDBUpdatesHandler cover the data
correctness use cases.
