Route Based on Attributes
This Processor is almost identical to the Route Data Based on Content Processors described above. It takes two different forms: One-to-One and One-to-Many, as do the Content-Based Routing Processors. This Processor, however, does not make any call to ProcessSession's
read method, as it does not read FlowFile content. This Processor is typically very fast, so the
@SupportsBatching annotation can be very important in this case.
