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

You could still use JGroups state transfer; getState() would list the state provider as target node. In general, partial state transfer involves transferring (1) the partial state and (2) the digest, which is a vector of highest seqnos seen for every member. When we get a partial state, we always overwrite our own digest with the one received, and update our state accordingly. However, when this is done a couple of times, for different partial states, I'm not sure that we won't receive a few messages multiple times, due to the digest overwriting... I think the cleanest solution would be for you guys to reuse the state transfer you already use for state transfer in distribution mode.
