One of the key pieces of the WSO2 ESB/EI development is the Mediation Sequence. Almost everything we develop is done inside sequences. Simply put, we can define a sequence as a way to group a set of mediators that will be used to handle the messages that arrive in the sequence. If we think of a Proxy Service or API, we usually have 3 sequences:
* inSequence: Process the message received until it reaches the backend service.
* outSequence: Process the response payload from the backend service until it reaches the client.
* faultSequence: Used for Error Handling.
From that, we can understand that the sequences will contain the mediators that will be used to transform/process the message until its destination (the end of the sequence). https://goo.gl/xGoh6S #DataIntegration #ML
