Using a user-supplied string as vertex ID
I'd like to specify unique string IDs for newly-added vertices in JanusGraph. I've verified that I can set graph.set-vertex-id to True and then add integer IDs via my (python) client as expected.
Does JanusGraph support user-specified string identifiers in any fashion? If not, is there a recommended way to map into integers (e.g., a potentially lengthy MD5 hash?) or will such a long number damage JanusGraph's ID indexing?
Thanks much for your time!
