 -   Multiple Active Result Sets (MARS). [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)] uses MARS for  read-only connections to tables with a columnstore index. However, [!INCLUDE[ssSQL14](../../includes/sssql14-md.md)] does not support MARS for concurrent data manipulation language (DML) operations on a table with a columnstore index. When this occurs, [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] terminates the connections and aborts the transactions.
