I have a cluster config that uses AMQP (RabbitMQ) to distribute events to other VM’s running on other nodes, and this is working just fine for regular command-causes-event scenarios.
Now, I’ve moved onto experimenting with Event Replay scenarios using a ReplayCluster in my Spring config.
I have successfully instructed my replay-cluster to start playback, and playback does occur - sending my stored events to the listener I have registered. However, none of these events seem to make it onto the AMQP Exchange that I’ve configured via my ‘terminal’ (the config is copied from a known-good Spring configuration which already works, just with <axon:replay-cluster line added to the cluster.
I can understand that it might be a terrible idea to ‘distribute’ replayed events, but I couldn’t see anything in the documentation for Axon that explicitly says it shouldn’t either be done or be possible, only that replay cluster wraps a regular cluster.
Have I missed something? Is the distributed replay of events such a bad idea that the framework prevents it from happening or have I misunderstood or mis-configured something?
Any help gratefully received!
