Cassandra/Scylla as graph database backen for JanusGraph and API exposed with GraphQl

Question

I am looking for a Graph database using Scylla or Cassandra as the backend and then expose the web api as GraphQl.

Can you help me verify that I have got the followin stack right:

1. GraphQl or TinkerPop // Api schema, exposing api
2. JanusGraph(privious Titan) // Database layer facilitating grap structure
3. Cassasndra or Scylla

Answer 1

You've pretty much got it right though just to help clarify:

GraphQL is an abstraction designed to help make development/data access a bit simpler for developers. You would have to create a service that translates GraphQL into Gremlin.

The stack you're envisioning looks like:

GraphQL -> Gremlin/TinkerPop -> JanusGraph -> DataStore (Cassandra, Scylla, etc).

As far as the datastore is concerned, JanusGraph is compatible with both Apache Cassandra and Scylla.
