Remarks

Hazelcast provides distribution mechanism for publishing messages that are delivered to multiple subscribers which is also known as publish/subscribe (pub/sub) messaging model. Publish and subscriptions are cluster-wide. When a member subscribes for a topic, it is actually registering for messages published by any member in the cluster, including the new members joined after you added the listener.

Messages are ordered, meaning, listeners(subscribers) will process the messages in the order they are actually published. If cluster member M publishes messages m1, m2, m3...mn to a topic T, then Hazelcast makes sure that all of the subscribers of topic T will receive and process m1, m2, m3...mn in order.

Methods

PublishAsync(T)	Publishes the message to all subscribers of this topic
SubscribeAsync(Action<TopicEventHandlers<T>>, Object)	Subscribes to this topic.
UnsubscribeAsync(Guid)	Stops receiving messages for the given message listener.
