Niko Neugebauer shows us something new in SQL Server 2019:
There has never been such information before!
We are just writing into it!
Why do we have those wonderful 1351498 logical reads ?
Are they actually writes ? And if they would be, would not it be correct to display them as physical accesses ?The answer is rather simple and actually should have been expected.
We are inserting a big amount of data into an empty table with a Primary Key, which triggers a creation/update of the statistics and those are the reads of the statistics scan operation.
I hadn’t noticed that, but it is quite interesting.
