The routing message processor scatter gather

Jan 21, 20170 likes361 views

Scatter-gather in Mule sends a request message concurrently to multiple targets. It then collects the responses from all routes and aggregates them into a single message. To implement scatter-gather, a flow references two sub-flows that will run concurrently. The payloads from both sub-flows are then merged at the end by the scatter-gather processor.

The routing message processor scatter gather

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

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 .

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 .

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

In my next slide I will bring some other techniques in Mule implementation .
Hope you have enjoyed this simpler version.
Keep sharing your knowledge and let our Mule community grow 

Quartz can be used in Mule applications to schedule events. An inbound Quartz endpoint triggers events that can be repeated, like every second. Outbound Quartz endpoints schedule existing events to fire at later dates. Cron expressions define schedules and events can be persisted in a database. Jobs perform actions when time triggers occur from the Quartz transport. For example, a Mule flow can be configured to write a file to an outbound endpoint at a specific interval defined by a Quartz scheduler.

Webservice vm in mulePraneethchampion

The document discusses decomposing a complex Mule flow into smaller parts using VM components. The VM transport allows breaking a large, complex flow into smaller pieces connected by queues for better control and performance. This helps control each event queue, reduces flow complexity, and prevents resources from being overcommitted. The example shows exposing a CXF web service by breaking the flow into two parts connected by a VM queue. It stores the SOAP action in a property before sending to the VM queue to preserve it for the second flow.

Mule propertiesGandham38

Mule properties files allow configuration values to be externalized and parameterized. Property placeholders can be used to reference values defined in properties files from within Mule configurations. Values for placeholders can come from global properties, property files, environment variables, or runtime arguments, with earlier sources taking priority over later ones. Properties files provide a way to manage configurations across different environments like development, testing, and production.

Mule with composite sourceAnirban Sen Chowdhary

The document discusses how a Mule Composite source scope can listen to multiple inbound endpoints in parallel and trigger a flow when any of the endpoints receive a message. It provides an example flow configuration that uses both a Quartz scheduler endpoint and an HTTP endpoint to trigger the same flow and print a log message. The Choice router is used to detect which endpoint triggered the flow based on the log output. In summary, a Composite source allows a single flow to be triggered from multiple inbound endpoints to perform the same task.

Groovy in MulePraneethchampion

This document discusses using a Groovy scripting component in Mule to add a delay to a flow. The Groovy component uses the sleep method to pause message processing for a specified time period. This allows holding the payload for a set interval before writing the file to the outbound location. The example flow reads a file from one directory, uses a Groovy script to sleep for 3000ms, then writes the file to another directory.

Testing muleSindhu VL

Mule provides tools for testing Mule applications at various levels: - Unit testing focuses on individual components without running Mule and uses MUnit. - Functional testing runs Mule with limited configuration to test flows, routing, and error handling. - Integration testing exercises the full application configuration similarly to a production environment. MUnit is Mule's testing framework that allows mocking message processors and endpoints to isolate components during testing.

Create dynamic json using muleSon Nguyen

This document discusses how to dynamically generate JSON payloads in Mule ESB flows. It shows how to use an Expression Transformer to generate a JSON string from flow variables and send it as a request to an external service. The JSON is constructed from flow variables that can be assigned values dynamically within the flow. Testing the flow by hitting a URL generates and posts the JSON, then logs the request and response. The Expression Transformer executes expressions to set the message payload, allowing dynamic JSON generation.

mule custom aggregatorPaolo Mojica

Creating a custom aggregator in Mule allows aggregating results from scatter-gather routing in a custom way. A class must implement the AggregationContext interface and override the aggregate method. This method accepts an AggregationContext with events from each route and the original event. The implementation should iterate events to access payloads, compose a new payload if needed, and return the original event with the new payload and any added properties. Understanding the AggregationContext parameters of events and original event is key to properly implementing custom aggregation.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

The routing message processor scatter gather

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.

3. Message Processor Message Processor Combined Payload 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. Keep sharing your knowledge and let our Mule community grow 
