Nodes that are a circle () are considered "Process Nodes" where, after unlocking the canvas, configurations can be made to the nodes and processed. Each process node has at least one output dataset that is typically a materialized table in the cloud environment that can be analyzed.
To configure a process node, unlock the canvas, left-click on the node and a configuration window will appear.
To delete a process node, unlock the canvas, right-click on the node, and select Delete. Processes cannot be deleted in some situations, as they are an immutable part of the workflow.
To remove a connection to a process node, unlock the canvas, left-click the linking arrow, and drag it away from the process node.
