The document discusses using the Splitter component in Mule applications. The Splitter splits an incoming message into fragments based on an expression and sends each fragment to the next processor. This allows processing message parts asynchronously and then reassembling them using an Aggregator. An example flow splits an XML shipment order message by item title and logs the results.

- 1. Splitter
- 2. Abstract The main motto of this PPT is How to use Splitter Component in our applications.
- 3. Introduction The Splitter Flow Control splits a message into separate fragments, then sends these fragments one at a time to the next message processor in the flow. Segments are identified based on an expression parameter, usually written in Mule Expression Language (MEL), but other formats can be employed also. You can then use aCollection Aggregator Flow Control to reassemble the parts of the original message. You can also include a Resequencer Flow Control to put the parts back into the original sequence in case they are shuffled out of order. Splitting and aggregating the message is especially useful when you intend to process the split parts in asynchronous flows running on separate servers. Together, the splitter and aggregator flow controls allow you to share the workload among several servers and still be able to reassemble the message after it’s processed.
