Folks, who knows if there are restrictions to add node filter for distributed Semaphore/Lock? I want to suggest this feature.
I met a case in personal experience: some grid services were filtered by nodes and launched over a logical sub-cluster. The services worked with caches being held in the same sub-cluster: the caches had the same node filter. I found that a distributed lock might be handy for the task I was doing. A distributed lock using within these grid services. No matter what the task was. It might be done without lock too. But I wandered I could not place the lock in the same sub-cluster. Other nodes, outer to that sub-cluster, should not held the lock at all. It looks strange to me. I believe most object run over caches. Caches can be configured with node filters. I think almost every object might be filtered where to keep it. Any ideas?
