             Summary: Guard ManagedRocksDB direct iterators against concurrent DB close (follow-up to HDDS-14800)
                 Key: HDDS-14856
                 URL: https://issues.apache.org/jira/browse/HDDS-14856
             Project: Apache Ozone
          Issue Type: Improvement
            Reporter: Priyesh K


HDDS-14800 fixed a TOCTOU race condition for the main volume iterator path by having {{ManagedRocksIterator}} hold the {{RocksDatabase}} reference counter for the full lifetime of the iterator. This prevents the DB from being physically destroyed while the iterator is in use.

However, the fix only applies to iterators created through {{{}RocksDatabase.newIterator(){}}}. Several components bypass this layer and call {{ManagedRocksDB.get().newIterator()}} directly, so the counter is never acquired and the same race window exists for those iterators.
