We wanted to combine point and polygons in one layer for display and performance reasons. So I thought you could just convert the points to circles or polygon approximations and update the feature service with that information. Is this possible?
I am not sure what you are getting at, but I can confirm you can have only one type of geometry in a feature layer. As a result, you can not mix point and polygons in one feature class. However, you can store point with radius specified as an attribute value and then make use of geometry engines's buffer method.
