Greetings<
Few of our tables in production server have few hundred million rows( between 200mil and 800mil). We add between 200,000 and 500,000 rows every week. Less than one percent of total rows each of them have. Most of these tables have chronologically increasing index columns like date or identity value. We run update stats on weekend for half a day. The weekend we run stats of large tables we are unable to run stats on other smaller tables .
Do I really need to run update stats every weekend on those large tables?
What is the best criteria I can use based on data changes so I can cover many other tables to refresh statistics?
Thank you & regards,
Sid.
