Query regarding the working of a message queue

[madhavi <ma...@gmail.com>]

Hi Professionals,

I have a design query reagrding queue. My scenario is as follows


I have to use a messaging system, with single producer and multiple
consumers(Asynchronous). The producer pushes different types of messages
into the messaging system. Depending upon the messagetype, that particular
consumer has to consume that message.(Each consumer is  running on a
different server). If, one consumer is down and a message comes for that
consumer will be in messaging system only. If, I use a message queue, the
message in the queue will block the next messages/ the next messages can be
consumed by the other consumers. Is queue suitable for handling this kind of
situations. Or do we need to go for a topic.
Any suggestions..

Thanks in advance

As I see it you have two choices:

1. Use selectors. Each broker would need to be network connected to the
producer's broker with a fetch size of one message which might well limit
performance but would avoid possible stuck messages.
http://activemq.apache.org/selectors.html

2. Use a different queue for each different type of message. I'd do this.
Far simpler provided you don't have a restriction on creating queues.
