WAN Replication Operation Timeout
After a replication event is sent to the target cluster, the source member waits for an acknowledgement that event has reached the target. If confirmation is not received inside a timeout duration window, the event is resent to the target cluster.
Default value of for this duration is 5000 milliseconds.
You can change this duration depending on your network latency. The Hazelcast Enterprise user can set the hazelcast.enterprise.wanrep.optimeout.millis
property to change the timeout duration.
You can do this by setting the property on the command line (where xxx is the timeout duration in milliseconds),
-Dhazelcast.enterprise.wanrep.optimeout.millis=xxx
or by setting the property inside the hazelcast.xml (where xxx is the requested timeout duration):
<hazelcast>
<properties>
<property name="hazelcast.enterprise.wanrep.optimeout.millis">xxx</property>
</properties>
</hazelcast>
