 --authenticationDatabase arg     user source (defaults to dbname)
 --authenticationMechanism arg (=MONGODB-CR)
                    authentication mechanism
 --dbpath arg             directly access mongod database files
                    in the given path, instead of
                    connecting to a mongod server - needs
                    to lock the data directory, so cannot
                    be used if a mongod is currently
                    accessing the same path
 --directoryperdb           each db is in a separate directly
                    (relevant only if dbpath specified)
 --journal               enable journaling (relevant only if

 --noobjcheck             don't validate object before inserting
 --filter arg             filter to apply before inserting
 --drop                drop each collection before import
 --oplogReplay             replay oplog for point-in-time restore
 --oplogLimit arg           include oplog entries before the
                    provided Timestamp (seconds[:ordinal])
                    during the oplog replay; the ordinal
                    value is optional
 --keepIndexVersion          don't upgrade indexes to newest version
 --noOptionsRestore          don't restore collection options
 --noIndexRestore           don't restore indexes
 --w arg (=0)             minimum number of replicas per write
