Hi there, I have trouble to understand how does the conduit subscriptions option work in a network of brokers. Below is a sample code that does the following:
* Create 3 brokers and network them: broker1 <> broker2 <> broker3 ** conduitSubscriptions option is set on every netwotk connector ** The ttl is set so that messages and subscriptions can go through all the brokers * Create 3 camel contexts with some routes that allow to: ** Post a message to the topic1 from any client connected to any broker ** Subscribes to topic1 from any client connected to any broker The unit test creates a Canel ProducerTemplate that posts a messages to topic1 from the broker1. As ActiveMQ and Camel are configured, and as far as I understand the conduitSubscriptions option, I would expect the message to be delivered to the mock endpoints only once on each. The result is quite confusing: * mockEndpoint1 receives 1 message * mockEndpoint2 receives twice the same message * mockEndpoint3 receives twice the same message In the ActiveMQ and Camel debug logs I can clearly see that the message is sent twice in the topic1 from broker1 to broker2 and same from broker 3 to broker2. It's expected that the topic1 subscriptions on broker2 and broker3 are propoagated to broker1, but I though it would be considered as a unique subscription from the broker1 perspective. This is not what seems to happen. It's annoying because it introduces duplicate messages then. I thought the conduitSubscriptions option was actually meant to fix this. I must be missing something here but can't see what.
