thanks mike
I don't think there's a way to determine this (upload from ArcMap or upload from shapefile) via the API so we'll just have to assume the lower value of 1000. fwiw, any reason why these two values are different?
also, are there any good paging samples out there? e.g. spatial search returns the max value of features, how do I get the rest of them? in other APIs, there's usually a page, offset or cursor variable that can be sent with subsequent requests to get the rest of the values. The only thing I've ever seen with the AGS REST api is to use the ID-Only queries and then cycle over all the returned values (which seems very inefficient, unless you could use an IN filter with a 1000 IDs)
cheers
