GetImplementingThingsWithData() performance issue for Large data set

Hi Folks,

@PaiChung @CarlesColl @Constantine 

I have 500 Things to fetch properties from.And I have already tried fetching the Things first and then query for required properties only. But it still takes lot of time to execute.

Is there any other way to fetch larger set of data from Things in a least possible time.

Note: Already tried below workaround but no luck.

         var ThingsList = ThingTemplates["Template"].GetImplementingThings();

              var params = {
                     types: "STRING" ,
                     t: thingsList ,
                     columns: "MachineNumber",
                     expressions: "Things[name].MachineNumber"
                      };
