Stairway To Columnstore Indexes

SQL Server 2012 and later offer a very different type of index from the traditional b-tree, the in-memory columnstore index. These indexes use a column-based storage model, as well as a new "batch mode" of query execution and can offer huge performance increases for certain workloads. But how are they built, how do they work, and why do they manage to have such a dramatic impact on performance? In this stairway, Hugo Kornelis explains all, with his usual mix of concise description and detailed demonstration.  Read more...

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.  Read more...

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.   Read more...
