MongoDB: How To Delete All Records Of A Collection in MongoDB Shell?

Question

I've tried

db.users.remove(*)

Although it returns an error so how do I go about clearing all records?

Answer 1

If you want to delete all records of a collection in MongoDB shell is by using the following method where the argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

Answer 2

If you want to eliminate everything you might be better off dropping the collection and it depends on whether you have user-defined indexes on the collection that means whether the cost of preparing the collection after dropping it exceeds the longer duration of the remove() call vs the drop() call.
