A week late and more than a few dollars short, this blog post is focusing on a few of the features announced for SQL Sever 2014.

Columnstore indexes were a big feature of SQL Server 2012, limited by the fact that they were static, meaning that you had to disable or drop and then enable/rebuild once updated.

So other than the exciting new features above, there was also information around some of the features that were introduced SQL Server 2012:
