Re: [infinispan-dev] Introducing JGroups scopes

Hmmmm, not sure about adding a method to IC, cos that would lead to code like this which is very verbose: cache.getAdvancedCache().getInvocationContextContainer().getInvocationContext().setScope("X") As a user, I'd prefer something like: cache.getAdvancedCache().withScope("X") However, this would only be used to attach a particular scope. I envision a global, cache manager level configuration such as that marks all caches in that cache manager to be scoped by the cache name. That way, HTTP session repl code would need no changing at all and with a single flag, they could make each individual cache to act in its own scope. The code above would allow two caches to share the same scope for those situations where we want sequential calls for the two caches, i.e.: cache1.getAdvancedCache().withScope("X") cache1.put() cache2.getAdvancedCache().withScope("X") cache2.put() By the way, I don't understand your comment of "refine this scope by adding GlobalTransaction and so on". If we take the cache1/cache2 example and imagine that these two would be called within a transaction, I'd imagine that the transaction itself would act as a scope and so would not need for a particular scope definition? i.e. tx.begin() cache1.put() cache2.put() tx.commit() At first glance, 5.0 would be the perfect target for this, but we'd need to take in account for any requirements coming from Paul since HTTP session repl could greatly benefit from it. As far as 2LC is concerned, within a deployment multiple txs will be operating on same caches so scoping could not be used. However different deployments could benefit from deployment level scoping so that messages for different caches can be sent in parallel. In AS environment different deployments could share the same 2LC cache manager and so the configuration option above would not work, but I'd need a deployment level scope that I'd use with cache.withScope().
