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
