 * scans the fields of `Query` and `Mutation` looking for fields annotated with the `@sql` directive and designates the specified
 * dataSourceStrategy to fulfill those custom queries.
 *
 * Note that we do not scan for `Subscription` fields: `@sql` directives are not allowed on those, and it wouldn't make sense to do so
 * anyway, since subscriptions are processed from an incoming Mutation, not as the result of a direct datasource access.
