The document discusses how to use the Splitter component in Mule applications to split an incoming message into fragments based on an expression. The Splitter sends the fragments to the next processor, and an Aggregator can then reassemble the original message. Splitting allows processing message fragments asynchronously across multiple servers. An example flow shows a message being split on the <item> tags of an XML payload and the split fragments being logged.

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.
