Columnstore Index - List of blogs on columnstore index published by SQL Server Product Team

SQL product team has made significant improvements in functionality, supportability and performance of columnstore indexes during SQL Server 2016. These improvements were prioritized based on the feedback by customer who had used columnstore index functionality in prior releases.

SQL Server product team has created a large set of blogs across multiple columnstore index scenarios. This blog consolidates the links as a one stop shop to access these. We will keep updating it as new blogs are added.  If you identify areas of columnstore that needs additional information, please feel free to contact us for suggestions
