Re: Leader election in a distributed situation?

I know nothing of this subject and was thus curious.
Did a search for "perl election leader" and came up with a .ppt file on something called "Zookeeper".

Then did a search for "cpan zookeeper" and the following showed up: Net::ZooKeeper - search.cpan.org

Is that at all helpful?

...the majority is always wrong, and always the last to know about it...

Insanity: Doing the same thing over and over again and expecting different results.

It isn't horrible, but it is an interface to the Apache library so there's a non-perl depdency there.

In the ideal case I'd be looking for Net::Master class, or similar, with helper classes for different transports. I've been sketching out a prototype using Net::Master::UDP just adding send/recv methods and keeping the logic in the main module, which seems like a good direction.

The biggest downside is that this is all async stuff, and I've little experience with perl and threading..

Update: I've got some simple code working for the case of UDP-broadcast only, using threads and threads::shared. I suspect this might be fragile, but I will see.
