Pavel Yaskevich commented on CASSANDRA-3271:
--------------------------------------------

If we will move to setBytes/getBytes that means that we will need to make 
BufferedMemory{Output/Input}Stream and on my opinion it kind of breaks idea of 
off-heap caches because we create such streams on each 
serialization/deserialization of the cache value so this re-buffering of the 
memory will be done all the time.
                
> off-heap cache to use sun.misc.Unsafe instead of JNA
