In the documentation for mongoDB it says: "Changed in version 3.0: The dropDups option is no longer available."
Is there anything I can do (other than downgrading) if I actually want to create a unique index and destroy duplicate entries?
please keep in mind the I receive about 300 inserts per second so I can't just delete all duplicates and hope none will come in by the time I'm done indexing.
