Subject Re: Cassandra memory consumption
Date Thu, 10 Apr 2014 19:35:14 GMT
Data structures that are stored off heaps:

1) Row cache (if JNA enabled, otherwise on heap)
2) Bloom filter
3) Compression offset
4) Key Index sample

On heap:

 1) Memtables
 2) Partition Key cache

Hope that I did not forget anything
