[jboss-dev-forums] [Design of JBossCache] - new eviction region issues

At the moment, when we create a new eviction region and there are nodes in the cache for the given region, these nodes won't ever be evicted as no eviction events will be placed in eviction queue. This does not seem as right behavior as the eviction polices will not do what are expected to - because they are not aware of the real number of nodes in the region, but the number of nodes managed after region's creation. To solve this I see to solutions: 1. forbid creation of regions which are not empty(through an exception) 2. populate eviction queue with create events for existing nodes Others? I vote for 1 as with 2 comes a number of complications: not all nodes were actually created at the same time; what if the number of existing nodes is greater than the max number of nodes the policy allows? These are issues that can only be resolved through assumptions - hard to explain to users and not always right for them.
