Well, in Gremlin, it is basically scripting, so you would probably do a loop and follow the pattern until you are at the right depth, see http://docs.neo4j.org/chunked/snapshot/gremlin-plugin.html#rest-api-flow-algorithms-with-gremlin for a flow algo that loops until the target node = sink, without any hard limitation.
