Weiwei Yang commented on HDFS-11601:

Thanks [~anu] for the heads up, I will keep an eye on the statues of rocksDB. I may not start
to work on this until we get to there. Let me decrease this one's priority for now on my list.

> The discussion in HDFS-11594 pointed to a potential issue that we might run into. That
is too many delete key operations can take place and make a DB slow. Running compactDB in
those cases are useful. Currently we run compactDB when we close a container. This JIRA tracks
a potential improvement of running compactDB even on open containers.
