Hi, After searching the internet for several weeks, I cannot find an efficient way to rank entities in a table. For example, if I store millions of scores of game plays in a table, and each score has an unique ID, how do I get the rank of a specific score? In other words, how do I find the rank of certain score by its unique ID?
Because each query only returns maximum 1000 entities, it would be a problem if the target score's rank is larger than 1000. If we add another column called rank, to track the rank of each entity, then it costs a lot of computation time to update rank if we insert a new score. Thanks for your help in advance.
