As it is said in the recent article "Google: Taming the Long Latency Tail - When More Machines Equals Worse Results" , latency variability has greater impact in larger scale clusters where a typical request is composed of multiple distributed/parallel requests. The overall response time dramatically decreases if latency of each request is not consistent and low. In dynamically scalable partitioned storage systems, whether it is a NoSQL database, filesystem or in-memory data grid, changes in the cluster (adding or removing a node) can lead to big data moves in the network to re-balance the cluster. Re-balancing will be needed for both primary and backup data on those nodes.

Hi, I'm trying to get several entries by key in a map, using a PredicateBuilder. The following code : IMap<Integer, Integer> map = Hazelcast.getMap("test"); map.put(1, 11); map.put(2, 22); map.put(3, 33);
