Aug 7, 2019 at 8:12 comment added hssay @TopLit Hard to give a general recommendation. But there are standard datasets like movielens grouplens.org/datasets/movielens/100k with ~1k user and movies. So that could be a baseline. Another thumb rule could be do you have atleast few hundred users which could be kept in validation set? Then recommendations approach could be used.
