I'm going to be introducing my new Politics gem at RubyConf 2008 tomorrow. This gem provides a few modules which solve a couple of distributed computing problems we were having at FiveRuns in providing fault tolerant, scalable processing across many machines.
Here's my RubyConf slides (1MB, Keynote), minus the screencasts I created to demo the two worker modules in action.
There are two modules provided:
TokenWorkerensures that one process from a group of redundant processes will be elected to perform processing for the next N seconds.
StaticQueueWorkerdistributes a predefined set of work to a dynamic set of processes every N seconds.
Both depend on the standard Ruby library and
StaticQueueWorker also depends on
net-mdns for Bonjour functionality.
You can find the code on github with a more detailed overview and examples of how to use the modules in your own code. If you find the software useful, please consider recommending me at Working On Rails.comments powered by Disqus
