Module database 

Valid federation 2 subgraphs.

Note: technically, federation 1 subgraphs are still accepted as input of composition. However, there is some pre-composition steps that “massage” the input schema to transform them in fully valid federation 2 subgraphs, so the subgraphs seen by composition and query planning are always fully valid federation 2 ones, and this is what this database handles. Note2: This does assumes that whichever way an implementation of this trait is created, some validation that the underlying schema is a valid federation subgraph (so valid graphql, link to the federation spec, and pass additional federation validations). If this is not the case, most of the methods here will panic.

federation_link

key_directive_name

The name of the @key directive in this subgraph. This will either return ‘federation__key’ if the @key directive is not imported, or whatever never it is imported under otherwise. Commonly, this would just be key.
