Usage:
  mongoimport <options> <connection-string> <file>

Import CSV, TSV or JSON data into MongoDB. If no file is provided, mongoimport reads from stdin.

Connection strings must begin with mongodb:// or mongodb+srv://.

                                                  that should be used to

                                                  increase sequentially
                                                  (foo.1,foo.0 would fail).
