SubqueryInterpreter

gql.server.interpreter.SubqueryInterpreter
class SubqueryInterpreter[F[_]](ss: SignalScopes[F, StreamData[F, _]], sup: Supervisor[F], stats: Statistics[F], throttle: FunctionK[F, F], errors: Ref[F, Chain[EvalFailure]], subgraphBatches: SubgraphBatches[F])(implicit F: Async[F])

The SubqueryInterpreter recursively runs through the AST and performs a multitude of tasks:

  • Runs the gql.resolver.Resolver/gql.resolver.Steps defined in the query.

  • Accumulates errors that occur during the evaluation of the query.

  • Logs streams that have been subscribed to.

  • Batches computations that have been marked as batchable.
