How to get the last N records in mongodb?

Question

I can't find anywhere it has been documented this. By default, the find() operation will get the records from the beginning. How can I get the last N records in MongoDB?

Answer 1

From your question it looks like, you want to sort in ascending order:-

For that, you can use sort() function:-

db.foo.find().sort({x:1});

If you pass the 1 as a parameter then it will sort in ascending order and if you pass -1 then it will sort in descending order.
