2. Scatter-Gather is an important component in Mule that sends a request message to
multiple targets concurrently. At the end it collects the responses from all routes, and
aggregates them into a single message.

Processing concurrently

5. To implement scatter-gather in Mule lets consider the following flow:-
You can see that there is two flow reference after scatter-gather which means it will
process 2 flows concurrently .

6. The other 2 sub flows are here:-
Now, You will see that these two flows will run concurrently and at the end the
payloads from both the flow will be merged .

7. Our Mule config will be as follow:-

8. Now, our flow is ready .. If we can test our flow using the url :-
http://localhost:8090/scattergather and we will get in logs as follows :-
You can see both the flow ended up concurrently and scatter-gather has
merged the payload fro both the flows at the end

9. In my next slide I will bring some other techniques in Mule
implementation .
Hope you have enjoyed this simpler version.
