------------------------------------

Hi [~anu]

I think we need to do some performance evaluation to get a better understanding the problem we deal with, then decide if we need or how to do compact properly at the backend. If you don't have plan to work on this anytime soon, you can assign it to me so I can do some work when other higher priority tasks are done. Thanks.

> 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.
