      Even though IT IS NOT RECOMMENDED TO STORE LARGE AMOUNT OF DATA IN USER PREFERECES, we tend to run out of space (see MDL-43739 and MDL-30668), which results in fatal errors. The solution to split the user preference into smaller chunks (for example in MDL-30668 we now store one value per course) only increases the session size. We need to be able to store larger user preferences.
