This topic describes the GraphQL schema definition language (SDL), based on the [GraphQL specification] (https://spec.graphql.org/October2021/) that Grafbase uses. It contains information about our implementation of the specification, as well as any slight deviations from the specification.

And repeat until
You can also start from the end of the list using
