Scatter gather flow in mule

1. SCATTER GATHER FLOW
IN MULE

2.  Note that, unlike All, Scatter-Gather executes routes
concurrently instead of sequentially. Parallel execution
of routes can greatly increase the efficiency of your
application and provides more information than
sequential processing. Refer to Migrating to Scatter-
Gather from the All Message Router below for more
information about the differences you can expect.

3. 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.

6. 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 .

7. 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 .

8. Our Mule config will be as follow:-

9. 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

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