> Most of the highest memory consuming data structure in Cassandra is now off-heap. It
will be nice to display the memory used by BF's, Index Summaries, FS Buffers, Caches and Memtables
(when enabled)
> This ticket is to track and display off heap memory allocation/used by running Cassandra
process, this will help users to further tune the memory used by these data structures per
CF.
