Enterprise WAN Replication
Replication implementations
Enterprise WAN replication has two different replication implementations. These are WanNoDelayReplication and WanBatchReplication implementations.
You can configure them using the configuration element replication-impl, as shown below.
<hazelcast>
<wan-replication name="my-wan-cluster">
<target-cluster group-name="tokyo" group-password="tokyo-pass">
<replication-impl>com.hazelcast.enterprise.wan.replication.WanNoDelayReplication</replication-impl>
...
</target-cluster>
</wan-replication>
</hazelcast>
<hazelcast>
<wan-replication name="my-wan-cluster">
<target-cluster group-name="tokyo" group-password="tokyo-pass">
<replication-impl>com.hazelcast.enterprise.wan.replication.WanBatchReplication</replication-impl>
...
</target-cluster>
</wan-replication>
</hazelcast>
WanNoDelayReplication sends replication events to the target cluster as soon as they are generated.
WanBatchReplication waits until:
- a pre-defined number of replication events are generated, (please refer to the Wan Replication Batch Size section).
- or a pre-defined amount of time is passed (please refer to the Wan Replication Batch Frequency section).
