Introduction to Message Sequence
When transmitting a large set of data, you might want to break it into smaller chunks in order to maintain system performance. The Message Sequence EIP facilitates this by sending data as a sequence of smaller messages and marking each message with sequence identification fields. For more information, refer to http://www.eaipatterns.com/MessageSequence.html.
How WSO2 ESB implements the EIP
When the sent request is large, WSO2 ESB by default breaks it into smaller chunks. In order to maintain consistency of the message, each chunk is then mapped with a sequence identity number so that its sequential order is not lost.
