[rabbitmq-discuss] Message filtering

[Vikram Viswanathan]

Hi,
     I have a requirement where my rabbitmq consumer needs to receive 
messages from a single queue based on a certain filtering criteria. 
Something like a jms, where I can create a consumer based  header 
property of messages.

    I do not want this to be done by exchange routing key, because this 
can mandate creating a large number of queues(I can possibly have a 
million routing keys)

    Is there a way to do it?

    BTW, How much memory is allocated for each durable queue created in 
the server ? Is there a way to tune this parameter ?

Thanks,
-Vikram
