[rabbitmq-discuss] dynamic binding

[PATAR, SAGAR]

Thanks.. It helped..

Just wondering what is the maximum number of binding Rabbit MQ supports and also does that depend on the resources like ram, disk space, processes rabbit mq is running

It looks like you are trying to modify an existing binding; I said...

>add a second binding with the new header value(s)...

Just use admin.declareBinding(newBinding),

...ending up with 2 bindings on the exchange, with the initial binding having the 1xxx matches and the new binding having the 2xxx matches.

I am using the below code and it is creating the binding object BUT is NOT reflecting on the admin console.. Attaching the src and context file for reference ..

Binding b = BindingBuilder.bind(q).to(e).with(binding.getRoutingKey()).and(bArgs);

Below is the configuration context file …

Yes; just add a second binding with the new header value(s); no need to do anything on the listener - it's all a function of the rabbitmq-server.

We are using header exchanges and are using spring-rabbit mq for configuration and binding listeners to listen to specific messages with specific message header values.
Ex: message header “srcId” has values “1001,1002,1003,1004”

At runtime if the same listener bean has to listen to messages with message header “srcId” having value “2001,2002,2003” ..
Is there a way to add these bindings dynamically at runtime ..??

Thanks
