SQL Server 2008 Filtered Index and xEvents

Just came across these bad boys, that can drastically increase your query performance as well as reduce the over head in the maintenance and storage costs of the index

 

CREATE NONCLUSTERED INDEX FIBillOfMaterialsWithEndDate     ON Production.BillOfMaterials (ComponentID, StartDate)     WHERE EndDate IS NOT NULL ;

Also just had my eyes opened to this new concept in SQL Server 2008 called xEvents

which can be helpful for performance reasons...
