FixedComplexityLimit sets a complexity limit that does not change.

AutomaticPersistedQuery saves client upload by optimistically sending only the hashes of queries, if the server does not yet know what the query is for the hash it will respond telling the client to send the query along with the hash in the next request.

ComplexityLimit allows you to define a limit on query complexity If a query is submitted that exceeds the limit, a 422 status code will be returned.

EnableIntrospection enables clients to reflect all of the types available on the graph.
