We use Elixir at CarLabs, and when we decided to start using a graph database, we noticed there were no libraries that let you manipulate your graph db in idiomatic Elixir. We started by exploring Neo4j, but moved to AWS Neptune. Since both of these, and most graphdbs support the Gremlin query language, we wrote Gremlex.
