-------------------------------------------------
I strongly agree with the approach-1 mentioned in the description unless there
is a reason not to take that approach.
> Simplify privilege cleaning
> ---------------------------
>
> Key: SENTRY-1556
> URL: https://issues.apache.org/jira/browse/SENTRY-1556
> Project: Sentry
> Issue Type: Improvement
> Components: Sentry
> Affects Versions: 1.8.0, sentry-ha-redesign
> Reporter: Alexander Kolbasov
> Assignee: kalyan kumar kalvagadda
> Priority: Minor
>
> The SentryStore class has a privCleaner that cleans up orphaned privileges.
> Currently cleaning is happening after 50 notification requests are sent and
> it uses locking to synchronize.
> I think the whole thing can be simplified:
> 1) We should consider whether it is possible to clean up a privilege simply
> when we see that there are no roles associated with it. In this case we do
> not need this at all.
> 2) We can simply run a periodic job to clean up orphaned privileges and
> groups (which are not cleaned up at all now).
