Cluster PubSub

The distributed publish subscribe feature solves the problem of sending messages to all actors in the cluster that have registered interest in a named topic. This feature is only enabled when the actor system is running in the cluster mode and the pubsub option is enabled.

How does it work?

Once the distributed publish subscribe mechanism is enabled,

• a TopicActor is started on all nodes in the cluster. This actor is not redeployed on node failure.
• Local node actors will send a Subscribe tell-message to the TopicActor. Successful subscription will receive SubscribeAck message. To unsubscribe the subscribed actor need to send Unsubscribe tell-message to the TopicActor. When the operation is successful the actor will receive UnsubscribeAck message.
• Local node actors after subscription can publish message to a named topic by sending Publish tell-message to the TopicActor. The published messages will be disseminated to all local subscribers and remote subscribers of the given named topic.
