Increase index_interval and reopen sstables on low heap situations ------------------------------------------------------------------
Key: CASSANDRA-2875 URL: https://issues.apache.org/jira/browse/CASSANDRA-2875 Project: Cassandra Issue Type: Improvement Components: Core Affects Versions: 0.8.1 Reporter: Héctor Izquierdo One of the reasons that can cause an OOM is key indexes. Of course you can tune it, but that's after your node has crashed. Events like repair can cause a much bigger memory pressure than expected on normal operation. As part of the measures taken when heap is almost full it would be good if key indexes could be shrank. I don't know how indexes are stored in memory but I guess it would be possible to remove entries without rereading all sstables. -- This message is automatically generated by JIRA.
