Gremlin Language Drivers

11. § Elevate Gremlin to a top-level citizen in the programming language of choice
§ GLV can work with any modern language
– Function composition
– Function nesting
§ Java and Groovy (native)
§ Python is the first non-JVM GLV
§ Others are coming soon (JavaScript, C#, Go)
§ SPARQL-Gremlin and SQL-Gremlin
