[jira] [Created] (HDDS-8316) SnapDiff: Persistent collection optimization

Hemant Kumar created HDDS-8316:
----------------------------------

             Summary: SnapDiff: Persistent collection optimization
                 Key: HDDS-8316
                 URL: https://issues.apache.org/jira/browse/HDDS-8316
             Project: Apache Ozone
          Issue Type: Sub-task
            Reporter: Hemant Kumar


To store the snapDiff and intermediate objects, we implemented persistent collections (List, Map, Set) backed by RocksDB. Currently we do individual RocksDb put for every add/put operation to the collection. Which results to lots of I/O. We can optimize it by using WriteBatch and do batch updates of like 1000 entries.
