> With offHeap cache being used to store data blocks and on-heap for index and
> bloom filters, exposing the stats from the individual caches through JMX will
> help understand the cache usage trend. Currently the combined cache stats is
> available through JMX which may not provide insight into the individual cache
> usage.
