Updating statistics sql server 2016
This effectively implies, on larger tables one would be running without updated statistics almost all the time as the threshold is too high as the tables get bigger.
As of 02/23/2016, it sounds like Trace Flag 8048 is also enabled by default in 2016. So, uh, if you have a bigger server to test stuff out on, be my guest.
The basic concept was: Here’s an abridged version of 10-20 million and 30-40 million rows, and how many modifications they took before a stats update occurred.
As the table gets bigger, the threshold for statistic update reduces.
For tables greater than 25,000 rows dynamic statistics is applicable.
I've got a few more thoughts on the topic this week, and I look forward to your comments.
