Streams are a key modelling components in PhixFlow.
Streams are configured through the Stream properties. Streams are connected to other modelling objects via pipes; see Pipe properties.
Types of Stream
There are several types of stream:

Calculate by Set streams are like calculate streams in that an output record is produced for each input record. But in addition a grouping can be configured on the input pipe which allows, for each record processed, related rows to be included in calculations.
Publishing Streams

When you make changes to a stream's properties or its attributes, PhixFlow publishes the changes to the stream data tables in the PhixFlow database. This happens automatically in the background. Publishing many streams or streams with many attributes can take some time, and may slow performance.
If the stream properties are set incorrectly, PhixFlow will not be able to publish the stream data to the database. If this happens, the
will report the publishing error. PhixFlow will also display an error message if you try to interact with the stream, for example to view its data or to run analysis. You must correct the stream properties, so that PhixFlow can retry publishing the stream. Insert excerpt _console _console nopanel true
