New Enhanced Column Store Index in SQL Server 2014 – Part 1

Column Store Index, which improves performance of data warehouse queries several folds, was first introduced in SQL Server 2012. Unlike regular indexes or heaps, which store data in B-Tree structure (in row-wise fashion), the column store index stores data in columnar fashion and uses compression aggressively to reduce the disk I/O needed to serve the query request. In this article, Arshad Ali talks about the new enhanced columnstore index feature in SQL Server 2014.
