[infinispan-dev] Integration between HotRod and OGM

[Mircea Markus]

Neither the grouping API nor the AtomicMap work over hotrod.
Between the grouping API and AtomicMap, I think the one that would make more sense migrating is the grouping API.
One way or the other, I think the hotrod protocol would require an enhancement - mind raising a JIRA for that?
For now I guess you can sacrifice performance and always sending the entire object across on every update instead of only the deltas?
