Unexpected behaviour when using columnstore index | Microsoft Connect
An item has very recently been published to the Microsoft Connect website with regards to an issue relating to Clustered Columnstore Indexes. Unexpected behaviour when using columnstore index | Microsoft Connect. Put simply there is inconsistent behaviour when returning the data on a table that is stored using a Clustered Columnstore Index and a table that is not. There is also an issue when using the “Include Actual Execution Plan” from Managment Studio.
