Ádám Szita reassigned HIVE-22820: --------------------------------- > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
