Re: [infinispan-dev] Infinispan S3 Cluster + Store Success ! (+serious performance problems)

Right now, the cache access is synchronous (org.infinispan.Cache extends ConcurrentMap) If you enable it, the cache updates are delegated to an asynch store decorator, queuing updates for periodic flushing. When this decorator flushes updates to the actual cache store, they are currently flushed in a batch (transaction like). This batch is then sent to the cache store... and emptied synchronously. If you want to implement an asynchronous interface, you have to implement it through all the layers or it will be "resynchronized". The cache store interface does not offer an asynchronous (Future<>) interface... IMHO, if you want to allow asynchronous access, you have to begin down there, and push it up to the AdvancedCache interface. The real added value of a completely asynchronous system is to apply it on the system level, like the HTTP NIO libraries or a Multithreaded layer (OS level like Grand Central / OpenCL). phil "
