Branimir Lambov updated CASSANDRA-11681:
----------------------------------------
Description:
Currently we set aside at most 512MB, chunk cache of 480MB. With CASSANDRA-5863
we should probably go higher, but we need to evaluate to what extent it makes
sense to prefer chunk cache over compressed OS page cache / row cache etc.
The size of the space reserved for pooled buffers outside the cache
{{ChunkCache.RESERVED_POOL_SPACE_IN_MB}} could also benefit from some tuning.
