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.

The columnstore index in SQL Server 2012 stores columns instead of rows, and is designed to speed up analytical processing and data-warehouse queries. Whilst columnstore indexes certainly do that effectively, they are not a universal panacea since there are a number of limitations on them. When used appropriately, they can reduce disk I/O and use memory more efficiently.
