This is related to another post I made about mapping 450,000 features onto the map. I moved to using a hosted feature layer, which massively helped the memory usage, but now I'm stuck as the shape file I uploaded to make the hosted feature layer doesn't have much information.
Is it possible to add a field / attribute to a feature based on another set of data, on the client side after I grab that hosted feature layer?
I have a large object from our DB that has colours, labels and etc... in it for the 450,000 features, one of those fields matches a value in the hosted layer, Objectdd = Objectd. When I create the renderer for the hosted feature layer I'd like to add a field / attribute into the feature so I know what it is, and later use it as a query point is this possible?
