My cluster configuration is a simple replicated-failback-static configuration that can be found in the example from the Artemis project given below. https://github.com/apache/activemq-artemis/tree/master/examples/features/ha/replicated-failback-static
My use case is that my cluster must have zero message loss when failing over. The only way to achieve this is with synchronous replication. The live server must not acknowledge a message as received and persisted until it has confirmed the message has been replicated to the backup. I setup two artemis instances. The master on my local, and the backup in a linux VM. I then used linux netem to simulate a latency of several seconds between the two machines. I then ran a test where I pushed many hundreds of messages onto a durable queue in a transacted session. My test confirmed that I was able to push the messages in a few hundred milliseconds, thus proving that the messages were not replicated to the backup server before the live server confirmed that they were successfully placed on the queue. Is this the expected behavior for this configuration? Is there another configuration which does the synchronous replication? If so can you point me to an example of this configuration? -- View this message in context: http://activemq.2283324.n4.nabble.com/Artemis-Replication-before-acknowledgement-tp4712215p4712279.html Sent from the ActiveMQ - Dev mailing list archive at Nabble.com.
