The directed pipe strategy can be used in a number of configurations, including reading from PhixFlow streams - see pipes for details. The example given on this page is for the commonest applicationmost common use case: reading data from a large table in an external database. When applying this technique to reading from a stream, apply the same steps except for Update query to use _keyList - no special configuration is needed from the source stream that is being read by the directed pipe.

Open the pipe cat and set the pip pipe execution Strategy to Directed:
