Vijay updated CASSANDRA-1945:
-----------------------------
Attachment: 0003-New_Cache_Providers-1945.txt
0002-Update_existing-1945.txt
0001-Config-1945.txt
I was trying to implement the BigMemory concept into Cassandra cache..... I was
trying BB for caching and the performance looks great, nearly 50% less
footprint in the heap
(org.apache.cassandra.cache.bblru.JMXByteBufferCacheProvider) and the
concurrent mark sweep shows better performance (tried @ multiple times w/t
similar conditions - CPU and memory usage).
I did a very basic testing....
I also tried ehcache (OSS version) and it had almost similar performance to the
existing cache but it has disk persistence so I have attached the Patch.
Let me know if you want separate ticket for BB cache. but i think this gives
the user flexibility to choose the cache_provider during startup.
NOTE: The Code Attached is for POC and needs some cleanup's.
Thanks You!
