[jira] [Commented] (CASSANDRA-3534) Enhance memory emergency pressure valve

    [ https://issues.apache.org/jira/browse/CASSANDRA-3534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13157390#comment-13157390 ] 

Jonathan Ellis commented on CASSANDRA-3534:
-------------------------------------------

Yes, I think the right approach is to remove this code once CASSANDRA-3143 is done.

> Seems like when these thresholds are reached we are trying to reduce the keycache and Memtable sizes, but in the trunk memtable is moved off-heap hence reducing that will not actually help.
> Reducing the keycache might help but we might want to provide a way to bring the cache level back to the configured value when the pressure goes away.
> Conversation from IRC: we might want to remove these setting all together after global keycache.
