I am currently using JanusGraph together with Gremlin.Net, and need to set up a Composite Indexes for my database. From what I understand this is typically done through the Management API provided by JanusGraphFactory. Since the my codebase is .Net, using the Embedded JVM version of JanusGraphFactory is not possible. Also, I would not want to create indexes manually through the Gremlin Console as the application needs to be automatically provisioned and configured in a cloud environment.
What is the best way to configure indexes for JanusGraph? Are there any configuration properties I have overlooked, or would it perhaps be possible to run a Groovy script with the necessary management commands on server startup?
