Hi Joe Thanks for this great article. I am not an R user, but I have played around with the Python wrapper and calling the Rest APIs from a web page using JS. Since you mention API calls, I am curious to find out whether it is possible to make asynchronous calls (like in Java script) or parallel calls to CAS from the client?. Since the Viya machine in most cases might have more processing than the R client, will this be an opportunity to parcel out some work to CAS, do something else in R in the meantime ( not depending on CAS) and then use results when they come back?
