Good Morning All,
I am in the process of designing my first project using JMS. So far,
I am using the Spring XBean support and ActiveMQ 5.0-SNAPSHOT to
exchange some simple messages between two network nodes to get my
feet wet and start understanding all the components.
I am now looking for some advice on how to architect this application
and am hoping the list can help me out! :-)
The requirements:
- multiple nodes sending "process this data" messages ("web node")
- multiple nodes consuming the above messages and doing work
("processor node")
- processor nodes broadcast messages containing status updates which
need to cause things like email notifications and various other data
updates
Basically, I am designing a special-purpose video site where users
upload video and it gets processed. The users need to receive a lot
of progress information.
How can I have a variety of "listeners" for a event-style message
(like "processing complete") but only have one of them process the
message? (e.g. I have a pool of consumers that send notification
emails, another pool that updates a status page and will eventually
add more.) My understanding of "topics" is that you can't force only
a single subscriber to handle each message.
Any thoughts/comments/suggestions you can provide would be very helpful.
Thank you,
A.
