Description

As of now every node in Columnstore cluster has WriteEngineServer process together with dbroot that allows the node to participate in data storage layer. In case of a horizontal scaling Columnstore needs a new cluster role that has read-only capabilities. This task is to define the parts needed by such read-only node in terms of processes and Columnstore configuration.
