How to reload the Most Frequently Used nodes back into in-me

nan2k_sweety Aug 10, 2007 5:05 AM

Hi,

The requirement for us is to keep only the MFU nodes in in-memory cache. We are planing to use LFUEvictionpolicy so that it removes least frequently used nodes. But the problem here is that when the server goes off and comes up again, how to make the cache loader load only the MFU data into in-memory cache. We doubt whether the LFUPolicy is persisting the counter status. Can anyone please help us on this.

No, eviction queues and counters are transient and do not survive beyond server restarts.

Hi ,

Thanks for your immediate response. But is there any way to persist those things and load it on restart? Can you provide some input on this please?We are struck here.

Thanks and Regards

Unfortunately no - this is transient information. If you want, create a feature request for this on jira.jboss.org and vote on it, but I can't see this feature being included anytime soon - unless you feel like implementing it and contributing it to JBoss Cache. :-)
