Interesting solution, if it works I'd go with it. Another option would be to use a debounce function.  So each time the zoom changes that function would be called but the actual logic would be delayed until the function hasn't been called in some user defined amount of time (maybe 200 ms would be good for something like this). I always copy the underscore.js debounce function when I need this: underscore.js  ... View more

Okay, you should be able to manually query the feature service for graphics (which will include attributes). I would load all features when the page loads and then query against those features based on the user input later.  Revised sample: // do this on page load let featureLayer = new FeatureLayer({   url: <FeatureLayer URL>,   outFields: ["*"] }); let allPolygons = [];         featureLayer.load().then(fl => {   featureLayer.queryFeatures().then(results => {     allPolygons = results.features;   }); });‍‍‍‍‍‍‍‍‍‍‍ // call this when user submits polygon to query against all other // polygons function findPolygons(searchPolygon, graphics){   // if there's no graphics then there are no intersections   if (graphics.length === 0) return [];   // test each of them using geometryEngine.intersects against the search polygon   return graphics.filter(graphic => geometryEngine.intersects(graphic.geometry, searchPolygon)); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I should mention that if the graphics returned by the manual query don't have attributes, you may have to pass in a Query to queryFeatures.  The query needs a .where of "1=1" and an outFields of "*."  Let me know if you run into difficulties with that. ...
