Description

Support for vertex / label schema generation via schema definition language (SDL)

SDL is a concise way of specifying the GraphQL schema.
It is an official specification of GraphQL and has a well-defined syntax.

If it can specify a part of the S2Graph Management function through SDL, it is expected to improve usability a lot.

Below is an example that supports GraphQL SDL in NEO4J (another graph db).
In this example, it is assumed that each type is a `ServiceColumn` and the name(ACTED_IN, IN_GENRE) defined in `@relation` is defined as `Label`.

type Movie {
  id: ID!
  title: String
  year: Int
  imdbRating: Float
  actors: [Actor] @relation(name: "ACTED_IN", direction: "in")
  genres: [Genre] @relation(name: "IN_GENRE", direction: "out")
}

type Actor {
  id: ID!
  name: String
}

type Genre {
  id: ID!
  name: String
}
