Hey Sean, for a while I hacked on an EM-based Riak client but didn't find the time to investigate it further.
So you can do several things with riak-ruby-client an EM: 1) Just use the client with EM.defer, putting it into other threads. That arguably voids the purpose of using EM, but at least defers the blocking I/O work to a pool of threads where it can be handled without blocking the reactor. 2) Write a backend for riak-ruby-client that utilizes em-synchrony and em-http to turn things into a more procedural workflow. That should be simple enough based on the net/http backend [1]. Be aware of the limitations of using fibers though, their stacks only fit 4K so keep your stacks small :) 3) You could also just use em-http-request, but that way you'd give up a lot of functionality that's already in riak-ruby-client. I'd recommend looking at #2, it looks like an easy path and should make for a great addition to the riak-ruby-client too. In my ideal world, there'd be a backend based on Faraday [2], so that the Ruby client wouldn't even have to worry about the underlying implementation, but you need to punch Sean Cribbs (very nicely) about that. Or you could just use Faraday instead of em-synchrony all along, since Faraday has a backend for em-http/synchrony already. Hope this helps.
