Column store technology

Column store technology can provide very substantial performance improvements on data warehousing workloads. This project investigated how to integrate columnar storage into SQL Server. The solution adopted was to add a new index type, columnstore index, that stores data column wise instead of row wise. Columnstore indexes first shipped in SQL Server 2012, significant enhancements were added in SQL Server 2014, and further improvements will be included in the next release.
