I wonder if I can do request-reply with this:

  • 1 hazelcast instance/member (central point)
  • 1 application with hazelcast-client sending request through a queue
  • 1 application with hazelcast-client waiting for requests into the queue

The 1st application also receives the response on another queue posted by the second application.

Is it a good way to proceed? Or do you think of a better solution?

Thanks!

    I made a test for myself and validated that it works well with certain limitation.

    The architecture is Producer-Hazelcast_node-Consumer(s)

    Using two Hazelcast queues, one for Request, one for Response, I could mesure a round trip of under 1ms.

    Load balancing is working fine if I put several consumers of the Request queue.

    If I add another node, and connect the clients to each node, then the round trip is above 15ms. This is due to replication between the 2 hazelcast nodes. If I kill a node, the clients continue to work. So failover is working at the cost of time.
