             Summary: Non blocking Callout Mediator (Call Mediator)
                 Key: SYNAPSE-975
                 URL: https://issues.apache.org/jira/browse/SYNAPSE-975
             Project: Synapse
          Issue Type: New Feature
            Reporter: Isuru Udana Loku Narangoda
            Assignee: Hiranya Jayathilaka


One of the major drawbacks in Callout mediator is, it does not leverage the non-blocking transports.
Send mediator which leverages the non-blocking transports, does not provide a simple way to
implement service chaining scenarios.

Idea of the the Call Mediator is to solve the above two concerns.

Call Mediator invokes the backend service in an asynchronous manner and return without waiting
for the response.
Mediation will be paused from that point.
When response is received, mediation flow resumes from next mediator placed after the Call
Mediator.

User will experience two major features with the Mediator.

* Service chaining scenarios will be much easier to implement.
* Since both request and response can be handled within a single sequence, can define reusable
sequences.
