About index_interval:

Are you sure of this? As I understand indexes, it's not required because 
this parameter defines an interval of in-memory index sample, which is 
created during C* startup basing on a primary on-disk index file. The 
fact that Heap usage is reduced immediately after C* restart seem to 
confirm this, but maybe I miss something?
