[jira] Updated: (CASSANDRA-1945) Use EHcache for row cache + disk spillover

     [ https://issues.apache.org/jira/browse/CASSANDRA-1945?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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!
