Re: [infinispan-dev] Cache size in memory

Have no time to contribute right now, I really need to clean up the qi4j store code before anything else... The design I use is very basic, I hijack the LRU eviction mechanism and the trigger is memory-size based. Each time I add or remove anything from the cache, I update the cache's memory size, that's all. I don' t even use a separate thread, I check the cache size after each operation. I did not test the effect of a transaction rollback or anything complicated. Regarding infinispan, I think it should be really simple to implement a callback specifying the metric used to evict. Right now eviction is triggered by a number of 'entries'. If 'entries' could be changed to 'megabytes' or '% RAM usage', I don't think there are a lot of changes to apply to the current code. (well, you still have to query the host application about the current metric value, but that should not be infinispan's business since this metric is hardware/image related). cheers, Phil On Tue, Apr 6, 2010 at 6:57 PM, Manik Surtani <manik(a)jboss.org&gt; wrote:
