Disabling Nodes in a Stream
Process nodes with a single input within streams can be disabled, with the 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 nodes. You can still open and edit the node
settings; however, any changes will not take effect until you enable the node again.
For example, you might have a stream that filters several fields, and then builds models with
the reduced data set. If you want to also build the same mode lsw ithout fields being filtered, to
see if they improve the model results, you can disable the Filter node. When you disable the
Filter node, the connections to the modeling nodes pass directly through from the Derive node to
the Type node.
