public interface LocalMapStats
extends LocalInstanceStats

Local map statistics. As everything is partitioned in Hazelcast, each member owns 1/N (N being the number of members in the cluster) entries of a distributed map. Each member also holds backup entries of another member. LocalMapStats tells you the count of owned and backup entries besides their size in memory.
