Table Statistics

Starting on Jan2022 release, in order to mitigate the I/O required to update the sys.statistics table, this table is no longer persisted. It has been changed into a table producing system function sys.statistics() and a system view sys.statistics. Hence it is also no longer possible to do updates or deletes on this table (to remove old statistics).

To query statistics information, see Querying statistics.
