    When the IGNORE_DUPS is set, the Data Mover ignores duplicate-row error messages from the database. This way, the script does not error out.

    This might be useful when you want to import data into a table that already has some data.

    When this command is used, the DataMover cannot perform bulk inserts. This will drastically reduce the import speed.
