Since I will only have 1 table with that many columns, and the other tables will be "normal" tables with max 30 columns, and the memory of 2K columns won't be that big, I'm gonna guess I'll be fine.
The data model is too dynamic, the alternative would be to create a table for each user which will have even more overhead since the number of users is in the several thousands/millions.
