I created a REST connection to an Excel file and it crapped out on me when I tried to go above 500 items. Mind you, this was just setting up the connection (not displaying anything).
What are the limits? Shouldn't I be able to set up a REST connection even if 12,000 items are contained in the data?
Is there a resource (book, article) that I can refere to for building REST connections/SOAP connections and limiting the data as it comes in?
