I would be interested.
Scaling is another thing that I'm interested in or
load balancing with failover. Ultimately, I'd like to
split the load across servers and if one of them goes
down the other server(s) would pick up it's load.
I've implemented a very simple algorithm in which the
servers join a group and send a simple message
requesting who is the current publisher. It then
backs off a random amount of time ( < 1 sec) and if
after a few requests it hasn't gotten a response it
claims to the be publisher and starts to publish.
In order to do load balancing I would have to move
this type of logic from the group level to the subject
Any other ideas/methods for handling this?
