My situation is this:
I have:
- a producer1 that produce an event each 10 seconds (as the samples provided
by muse)
- a consumer1 subscribed to producer 1
- a producer2
- many consumers subscribed to producer2
The following in my scenario:
when consumer1 receive message from producer1, it must publish this event to
consumers subscribed to producer2, how can I call publish method on
producer2 from consumer1?
Producer1--(notifyEvent)--->Consumer1--(receive message and publish this
message on producer2)
