I don't know why, but I poorly named the "rebinding" feature in Gremlin Server:
http://tinkerpop.incubator.apache.org/docs/3.0.1-incubating/#_rebinding It's a horrible name for something that could have been easily referred to as an "alias". I'd like to deprecate "rebindings" for this better term and hopefully see that in place for 3.1.0. https://issues.apache.org/jira/browse/TINKERPOP3-913
