Thanks for the input, James. I'm using Postgresql so I don't think there is a DB vendor solution. Are you suggesting to create different topics for each datacenter or share the same topic across all the datacenters?
You could use either really; the important thing is that each data centres's messages get sent to every other data centre.
One of the issues I'm having is exactly where the brokers will be at each datacenter. I don't have extra hardware for the brokers so they'll have to live on the Tomcat servers. My first thought was to make them run as resources within the Tomcat instances. Are you aware of any issues setting up a Master/Slave configuration this way?
No - you can run them anywhere. Having a master/slave broker inside each Tomcat is a good idea. Then if the Tomcat running the master dies, one of the slaves will take over.
I forgot to mention previously that the number of datacenters may grow in the future so it would be nice if the solution required a minimum of changes to add a new datacenter.
Setting up a network of brokers is pretty straightforward, its only a single URL that changes in the config as you add data-centres. -- James ------- http://radio.weblogs.com/0112098/
