SQL Server Incremental Statistics in SQL 2017
Starting with SQL 2014, Microsoft offered another great feature called Incremental Statistics.
If you need to update statistics on a very large table with a FULLSCAN mode, it may take forever to finish. Performance degrades, Client confidence also reduces.
Keeping that as an area of concern, Microsoft introduced this feature and through this partitions will be created in the tables and whichever partition we want we can just run the update stats on that partition alone.
Previous all versions did not have this flexibility and instead, the only choice which was available was to run a FULLSCAN.
Summary:
Incremental Statistics are only meaningful for the partitioned tables.
If you can’t partition your table, this solution is not for you
Limitations / Not supported:
Statistics created with indexes that are not partition-aligned with the base table.
Statistics created on AlwaysOn readable secondary databases.
Statistics created on read-only databases.
Statistics created on internal tables and on views.
Statistics created with spatial indexes or XML indexes.
Statistics created on filtered indexes.
