Disabling Nodes in a Stream
Process nodes with a single input within streams can be disabled, with t he result that the node is
ignored during running of the stream. This saves you from having to remove or bypass the node
and means you can leave it connected to the remaining node s. You can still open and edit the node
settings; however, any change s will not tak e effect until you ena ble the node again.
For example, y ou might have a stream that filters s everal fields, and then builds models with
the red uced data set. If you want to also build the same models without fields being filtered, to
see if they improve th e model resul ts , you can disable the Filter node. When you disable the
Filter node , the connections to the modeling nodes pass directly through fro m the Derive node to
the Type node.
