public interface LocalMapStats
extends com.hazelcast.instance.LocalInstanceStats
MemberState
implementations.
As IMap
is a partitioned data structure in
Hazelcast, each member owns a fraction of the total number of entries of a
distributed map.
Depending on the IMap
's configuration, each
member may also hold backup entries of other members. LocalMapStats
provides the count of owned and backup entries besides their size in memory.

int 
getBackupCount()
Returns the number of backups per entry.

long 
getBackupEntryCount()
