Subject heap usage
Date Fri, 15 Feb 2013 09:06:12 GMT
Hi,

recently we are hitting some OOM: Java heap space, so I was investigating
how the heap is used in Cassandra 1.2+

We use the calculated 4G heap. Our cluster is 6 nodes, around 750 GB data
and a replication factor of 3. Row cache is disabled. All key cache and
memtable settings are left at default.

Is the primary key index kept in heap memory? We have a bunch of keyspaces
and column families.

Thanks,
Rik
