Processes can filter or manipulate data passing through them. A pipeline can include multiple processes in one or more routes, and each process sees every record passed to it from the previous node in the pipeline. If a process is a filter, it can be used to decide what to send on to whatever is next (from left to right) in the pipeline. Other processes can add to or change data or perform numeric evaluation of fields to determine if or when to pass on records.
The output of a Process can be one or more other Processes or one or more Targets. For more information, see Add Processes to Pipelines.
