While the Query Planner is automatic, it sometimes struggles with For Loops or complex Server-side ViewModels where it cannot "see" the data requirements deep inside a loop before it starts.

ExecuteFetchHints allows the developer to give the system a "heads-up." It executes expressions found in any ViewModel nesting that starts with the name "fetchhints". This pulls all necessary data into memory upfront so the loop can run at high speed
