    Description

      The use case from astronomical research team at CalTech:
      using aggregation pipeline, check what objects other data catalogs contain for the same position in the sky. (Now they are matching 4 million objects across 30 catalogs, and the number of catalogs is going to grow). The position can be described as a circle on sphere in both collections. Need to identify if there is an intersection of those circles.
