[infinispan-dev] Put Command

Hi I am modifying cache with freshness and consistency parameters for QoS. I want to know how an update to a database is done when cache is in invalidation mode and when it is in replication mode(both sync, async) Can some one please send me a simple algorithm of an update/modification Infinispan in Invalidation Mode when I want to insert/modify some data with ejb entity, 1 Does it invalidate data in the cache and then goes to the database and update over there? Infinispan in Replication Mode when I want to insert/modify some data with ejb entity, 2. Does it replicate data(in local and Across the cluster ) and then update the data to the database? what happens in case of failure. Thanks Meena Rajani
