Hi, When I switch a big table from STCS to LCS, I notice high off heap memory usage using nodetool cfstats. "*Off heap memory used (total)*" shows +10G usage.
Eventually my nodes died because of OOM. How do I throttle off heap usage? The only thing I see in cassandra.yaml is *memtable_offheap_space_in_mb. *Is that the only knob? Thanks.
