Re: [infinispan-dev] Partial state transfer in Infinispan

We use partial state transfer not to generate partial state per cache, but the entire state per cache, but since we have > 1 cache sharing a given JGroups channel, as far as JGroups in concerned this *is* partial state of a node. I.e., the state of just 1 cache on a channel, not all the caches. So we actually use cacheName as the state identifier (in JGroups' ExtendedMessageListener). But yes, there is no reason why we can't replace this with RPC as per Distribution, however I think we do need a streaming solution - not just for replication but distribution as well. As such I'd only want to re-implement this bit once, rather than a temp RPC based solution first. So we need a mechanism to either: (1) open a separate TCP socket for the sake of streaming state, or (2) reuse the sockets JGroups opens. They both have their pros and cons. (1) is more configuration, firewall setup, and a spiderweb of connections in a large grid (2) would mean multiplexing with JGroups' use of the socket. Any thoughts and suggestions?
