      Description

      mongodump's --forceTableScan option doesn't appear to ensure that the dumped documents are going to have unique _ids in the case where a document gets moved during the dump. I suspect that this will mess up mongorestores.

      Either mongodump should de-duplicate, or mongorestore should de-duplicate, or this option should go away (or stop being documented).
