GraphQL API for Apache TinkerPop supported Graph Databases.
Invana Engine is the core component of the back-end of the Platform. It contains the Python SDK to perform CRUD and Query operations on the Graph databases.
In theory any database that supports Apache TinkerPop's Gremlin 3.4.x shall work with Invana Engine. Vertex/Edge Id resolution needs to be fixed to add any new database support.
