[rabbitmq-discuss] Filter out messages from self

Wed Jun 20 19:38:06 BST 2012

Afternoon Everybody,

I would like to implement a feature where a Rabbit client does not receive any messages published by itself. The client will be listening on an exclusive Q that is bound to exactly one exchange.  That exchange will be bound to multiple exchanges.

I am about to implement this feature by filtering the messages after they have been received by the client using the props builder to identify the sender, but, I would like to know if there is a silver bullet that I have overlooked - some way to avoid receiving the messages in the first place (without cludging together all of the "other users" as binding keys).

Any quick fix that I am ignorant of?

Using:
Rabbit 2.8.1 broker running on Ubuntu 11
Java and C++ clients
persistent topic exchanges
persistent Qs

Flow:

User1_Q1 ->publish-> Ex99
User2_Q2 <-receive <- Ex2 <- Ex99
User3_Q3 <-receive <- Ex3 <- Ex99
User1_Q1 <- Ex1  x receive x   Ex99 //user who publishes message does not receive

User3_Q3 ->publish-> Ex99
User1_Q1 <-receive <- Ex1 <- Ex99
User2_Q2 <-receive <- Ex2 <- Ex99
User3_Q3  <- Ex3  x receive x  Ex99 //user who publishes message does not receive
