Chapter 8. Routing Output Data

Basic Fragment Splitting: A dumb split allows you to split fragments from a message and route them to a file, without performing any transformation on the split message fragments before routing. Basic splitting and routing involves defining the XPath of the message fragment to be split out and the defining a routing component (for example, JBoss ESB or Camel) to route that unmodified split message fragment.

Complex Fragment Splitting: Basic fragment splitting works for many use cases and is what most splitting and routing solutions offer. Smooks extends the basic splitting capabilities by allowing you to perform transformations on the split fragment data before routing is applied. For example, merging in the customer-details order information with each order-item information before performing the routing order-item split fragment routing.

In Stream Splitting and Routing (huge message support): Because Smooks can perform routing in stream (not batched up for routing after processing the complete message), it is able to accommodate processing of huge message streams that are gigabytes in size.

Multiple Splitting and Routing: Conditionally split and route multiple message fragments (different formats XML, EDI, Java etc) to different endpoints in a single filtering pass of the input message stream. For example, routing an OrderItem Java object instance to the HighValueOrdersValidation JMS Queue for order items with a value greater than $1,000 and route all order items (unconditional) as XML/JSON to a HTTP endpoint for logging.
