SQL pool exposes many of the SQL Server dynamic management views (DMVs). These views, when queried in dedicated SQL pool, are reporting the state of SQL Databases running on the distributions.
SQL pool and Analytics Platform System's Parallel Data Warehouse (PDW) use the same system views. Each DMV has a column called pdw_node_id, which is the identifier for the Compute node.
Note
To use these views, insert 'pdw_nodes_' into the name, as shown in the following table:
