[jira] [Updated] (CASSANDRA-12662) OOM when using SASI index
[ https://issues.apache.org/jira/browse/CASSANDRA-12662?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

---------------------------------------
Fix Version/s: (was: 3.6)
3.x
> OOM when using SASI index
> -------------------------
>
> Key: CASSANDRA-12662
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12662
> Project: Cassandra
> Issue Type: Bug
> Environment: Linux, 4 CPU cores, 16Gb RAM, Cassandra process utilizes ~8Gb, of which ~4Gb is Java heap
> Reporter: Maxim Podkolzine
> Priority: Critical
> Fix For: 3.x
>
> Attachments: memory-dump.png
>
>
> 2.8Gb of the heap is taken by the index data, pending for flush (see the screenshot). As a result the node fails with OOM.
> Questions:
> - Why can't Cassandra keep up with the inserted data and flush it?
> - What resources/configuration should be changed to improve the performance?
