Managing the size of Data Dictionary tables (sometimes called logs) can help improve performance. Teradata Database does not delete system data on its own so you must manage the logs and tables yourself. Determine what you should archive and what you should delete as needed for your site. (With respect to keeping Data Dictionary data for historical purposes, archive tables using a Backup Application Software solution.)
