Riak would be a poor choice as backend for Titan. The graph calculus used in gremlin et. Al. requires bounded and ordered set result semantics which riak cannot do well or fast or maybe at all.

Unfortunately it doesn't sound too encouraging, but I hope you will get around to looking into Titan integration.

All that said, we have been asked by a customer to look at integration with Titan, and when time permits, we will.
