Jonathan Ellis commented on CASSANDRA-3534:
-------------------------------------------
Yes, I think the right approach is to remove this code once CASSANDRA-3143 is
done.
> Enhance memory emergency pressure valve

> Key: CASSANDRA-3534
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3534
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.1
> Reporter: Vijay
> Assignee: Vijay
> Priority: Minor
>
> 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.
