Vijay updated CASSANDRA-1969:
-----------------------------
Description:
Java BB.allocateDirect() will allocate memory out of the GC region and will
help reducing the GC pressure on the JVM.
>From some of the basic tests it shows around 50% improvement than doing a
>normal Object cache.
In addition we can provide the users an option to choose BB.allocateDirect or
store everything in the heap.
Priority: Minor (was: Major)
Environment: Linux and Mac
> Use BB for row cache - To Improve GC performance.
