Parallel Data Warehouse exposes many of the SQL Server dynamic management views (DMVs). These views, when queried in Parallel Data Warehouse, are reporting the state of SQL Server databases running on the distributions.
Each of these DMV's has a specific column called pdw_node_id. This is the the identifier for the Compute node.
Note
To use these view, insert ‘pdw_nodes_’ into the name, as shown in the following table.
