WAN Replication Batch Size

When WanBatchReplication is preferred as the replication implementation, the maximum size of events that are sent in a single batch can be changed depending on your needs. Default value for batch size is 50.

To change the WanBatchReplication batch size, use the hazelcast.enterprise.wanrep.batch.size property in Hazelcast Enterprise.

You can do this by setting the property on the command line (where xxx is the batch size),

-Dhazelcast.enterprise.wanrep.batch.size=xxx

or by setting the property inside the hazelcast.xml (where xxx is the requested batch size):

<hazelcast>
  <properties>
    <property name="hazelcast.enterprise.wanrep.batch.size">xxx</property>
  </properties>
</hazelcast>
