Brian Towles commented on SENTRY-2030:
--------------------------------------
I think thats reasonable. My main concern would be synchronization in an HA
deployment. But honestly I dont feel that nodes being different by up to a
minute or so is a major issue, As long as a reasonable TTL is put in place for
the cache.
What about making it a configurable option that defaults to enabled?

> URL: https://issues.apache.org/jira/browse/SENTRY-2030
> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 2.0.0
> Reporter: Alexander Kolbasov
>
> Sentry is using a new persistence manager instance per transaction and
> repeatable-read transaction isolation level (except for Oracle). I think we
> can safely enable first-level caching (which is at the PersistenceManager
> level) which should improve performance without introducing any issues.
