As far as I understand CMAPI follows the MDB master that in its turn is switched by MaxScale. The CrossEngine section in Columnstore.xml becomes mandatory for the cluster b/c the credentials from the section are used by CMAPI to check whether localhost MDB is a master or not. |

MaxScale provides this function. Use of MaxScale is mandatory for ColumnStore clusters beginning with 1.5 |
