The Splitter component partitions incoming messages into multiple parts that can be processed independently. The Mule Collection Splitter splits a message into fragments using an expression, then sends the fragments one by one to the next processor. A Collection Aggregator can then reassemble the original message after asynchronous processing on separate servers. Configuration involves setting the display name, enabling correlation, and mapping message attributes like ID and correlation.

2. WHAT IS A SPLITTER?
• The Splitter is a component whose role is to partition a message in several parts,
and send the resulting messages to be processed independently. Very often, they
are upstream producers in a pipeline that includes an Aggregator.

3. MULE COLLECTION SPLITTER
• 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 a Collection 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.
