Subject Re: benefits of off-heap (serializing) row cache?
Date Thu, 22 Sep 2011 07:57:25 GMT
I think the cassandra team did not re-implement their own GC. I guess what
they meant is the less heap being used, the better GC performance.

AFAIK, only data that is not been updated frequently can benefit from
off-heap row cache, because when a row is modified, the row inside cache
need be invalidated.
