I have a Teradata system running which has a lot of data churn. Millions of rows per day. Currently we refresh the stats once a week. Does anyone have experience of running with such a system and can suggest when and how we should refresh stats? In my Oracle days #shudder we ran refresh jobs as and when during the day especially when tables had significant insert/delete activity. Is this possible in Teradata? I've noticed a AutoStats feature but not sure of it's capabilities. Any advice would be greatly appreciated.
