---------------------------------
> Proactive LLAP cache eviction
> -----------------------------
>
> Key: HIVE-22820
> URL: https://issues.apache.org/jira/browse/HIVE-22820
> Project: Hive
> Issue Type: Improvement
> Components: llap
> Reporter: Ádám Szita
> Assignee: Ádám Szita
> Priority: Major
>
> Currently LLAP cache eviction is only based on an eviction policy, that is
> reactive in a way that it only evicts buffers whenever there's space required
> for new ones.
> It does not take for example dropped entities (partitions, tables or even
> dbs) into consideration. We should also implement a proactive side of the
> eviction that does this for us, and in turn could increase overall cache hit
> ratios.
