Thank you jskinner-esristaff for the response. Would this be the method to Join SQL Server Tables with a reference Geodatabase based on a Unique identifier and upadate records in a one or more feature classes? This is currently a manual process. We export a table of attributes from SQL, we join with a reference feature class, create a new feature class of only of joined features, and then publish to REST. I understand that registering the Geodatabase as a Data Store with ArcGIS Server will keep the REST updated when features are changed. I am wondering how to automate the creating of the features based on the change in the SQL table views (although it can be made spatial views we are finding it too slow).
