-------------------------------------------
ohh that's pretty cool. I'll set myself a reminder to take a look at that and
test it out.

> Hey,
> I don't know if this is expected behavior, it seems like it may be but on the
> off chance it isn't : When sending a request to gremlin-server with
> {{opProcessor = 'session'}} the session is properly created but the
> initializing scripts set in the {{gremlin-server.yaml}} configuration are run
> every time. Resulting in the following warning:
> {code}[WARN] GremlinExecutor - Could not initialize gremlin-groovy
> ScriptEngine with scripts/generate-classic.groovy as script could not be
> evaluated - javax.script.ScriptException: java.lang.IllegalArgumentException:
> Vertex with id already exists: 1{code}
> This comes from the fact that {{scriptEngines}} are loaded on session
> creation. I'm guessing this is required? But running initializing scripts
> could be dangerous.
