Columnstore Indexes – part 126 (“Extracting Columnstore Statistics to Cloned Database”)

Read Original

This technical article details a new feature in SQL Server 2019 CTP 2.0 that allows automated extraction of Columnstore Index statistics when using DBCC CLONEDATABASE. It explains the previous limitation where these statistics were not persisted in clones, demonstrates the problem with a practical example using a TPCH database, and shows the new behavior and its importance for accurate query cost estimation.
