One day my boss came to me and my colleague Ron Avraham and said “We need to step up our game”. We were working on this GIS project using Esri ArcGIS API 4.0 for JavaScript, and our client woke up in the morning with an experimental mood. They wanted a new feature that will visualize a large number of entities on the map, and update their location-property frequently. They were talking about 10,000 entities moving on the map with their location updated every 0.5 seconds.

I was wondering whether ArcGIS API can handle this situation using the good old FeatureLayer
