Is there are any solution for round robin through HAproxy to Riak using protobufs? I believe Yammer guys are using it in their setup.. Might be wrong, though.

(Had httpchk for /ping to ensure the node is up) In my own testing with basho_bench this seemed to work, I'm unsure of what drawbacks there would be because I could not find any other then HTTP was slower then PBC. I did find find that Protobuffers did not roundrobin correctly with haproxy using tcp mode... darn :( So if we're just speaking HTTP could totally use HAProxy or a Hardware Load balancer to spread out the load.

The Ruby client still contains some things that reflect my earlier, less astute understanding of how a Riak client should behave and doesn't include obvious things like retrying requests (possibly on other nodes), conflict resolution strategies, and mutators. In the past, I have recommended that users put a lightweight load-balancer (e.g. haproxy, pound) between their application and Riak, and simply have the app connect to the locally-running instance of the LB. I realize this is not a great solution, but it also avoids a little NIH for now.

If I have several riak servers on a cluster, and want to distribute load fairly evenly, and am using the Ruby Riak client, what is the best way to balance load? With the HTTP interface, I can randomize the choice of host for a request. How would I do the same with the ruby client? Would I create a Riak::Client for each host, and then just randomize the selection of those for a given call? Do the clients contain any state that would make this a bad idea? Or is there a better way to do this?
