Frage
Is there a way to interact with a neo4j graph db (running externally HA mode) via Rexter API. Neo4j's REST api is great but using Rexter makes my application completely agnostic of the remote graph db implementation stack. This will enable me to swap in other tinkerpop based graph db stacks like titan without affecting/changing my application code.
