Class PartitionReplica

java.lang.Object

com.hazelcast.internal.partition.PartitionReplica

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public final class PartitionReplica
extends Object
implements IdentifiedDataSerializable

PartitionReplica represents owner of a partition replica in the partition table.

A PartitionReplica is identical to a Member which has the same address and uuid.

Existing Member interface could be used instead of introducing PartitionReplica class but Member has many additional attributes and functionality which adds complexity to maintenance of partition table.

Since:

3.12
