  2. Click "Show plan as text".

    Query plan
    QueryPlan {
     Parallel {
       Fetch(service: "listings") {
         {
           featuredListings {
             id
             title
             description
             costPerNight
           }
         }
       },
       Fetch(service: "reviews") {
         {
           recentReviews {
             id
