The answer to the above questions is the introduction of a new concept called 'vcores' – short for virtual cores. Number of vcores has to be set by an administrator in yarn-site. xml on each node.
VCORE: A unit of compute capacity for processing on CloudHub, which is equal to one virtual core. Up to ten Mule Applications can be deployed for every VCore purchased. Each worker is a dedicated instance of Mule that runs your integration application. Workers have the following characteristics: Capacity.
CloudHub is an Integration Platform as a Service (iPaaS). It enables you to deploy and run the application in the cloud via Runtime Manager. CloudHub is a scalable, multi-tenant, elastic, secure, and highly available iPaas. CloudHub is managed via the Runtime Manager console in the Anypoint platform.
What is Mule Worker? Worker is a dedicated Mule instance that runs the integration applications deployed to CloudHub. Workers has some characteristics. Each worker has the size and specific amount of capacity to process the data. Each worker runs in a specific cloud region like US, EU, etc.
According to the price-tracking website ITQlik, MuleSoft pricing starts at approximately $80,000 a year. However, the price that most enterprises pay is closer to $250,000 a year.
Mule runtime engine includes an embedded API gateway. API gateway allows you to add a dedicated orchestration layer on top of your backend APIs and services to help you separate orchestration from implementation concerns.
The Anypoint Platform control plane provides a set of cloud services that simplify the design, reuse, and management of integrations and APIs. These cloud services are available in a multi-tenant environment of the Anypoint Platform in the U.S. and EU regions.

- when you pull in a transform message component the default output type is payload for that. like this.
- click on the edit current target (pen) option which will open an selections dialog and under the output dropdown select Variable and supply a variable name:
For logging, Mule ESB uses slf4j, which is a logging facade that discovers and uses a logging strategy from the classpath, such as log4j2 or the JDK Logger. By default, Mule includes log4j2, which is configured with a file called log4j2. xml.
Debugging Mule Application With Anypoint Studio
- In the Package Explorer pane, right-click on your application, then select Debug As > Mule Application.
- To go to next step of debugging, click the Run to processor icon as highlighted in below snapshot.
- To resume execution, click the Resume icon (see below) or press F8.
What does to the attributes of a Mule event happen in a flow after an outbound HTTP Request is made? Attributes are replaced with new attributes from the HTTP Request response.
The Mule message, #[message] is the data that passes through an application via one or more flows. It consists of two main parts: The message payload, which contains your business-specific data.
Mule HTTP Listener The HTTP Listener Connector provides the most practical way to listen for HTTP requests. The connector can be set up to accept any request, or to only accept requests that are addressed to a very specific URI. You can choose what methods the connector can accept (GET, POST, etc).
- If you are using Mule 4 you can use typeOf().
- In a Transform Message you put:
- {
- typePayload: typeOf(payload),
- typeKey: typeOf(payload.value)
- typeVar: typeOf(vars.number)
- }
- between the parentesis you put the thing of you want the type.
DataWeave 2.0 pushes Mule 4 messages right into a connector, rather using MEL. To have greater data transparency, Mule 4 stores the event structures and responses (data and context). In contrast to Mule 3, Mule 4 DataWeave avoids the stress of converting data objects to Java objects by the usage of expressions.
In Mule 4 the payload, attributes and variables are part of the Mule Event. The payload and attributes are in the message. The message and variables are in the event. Both the message and the event are immutable.
Mule 3 message structure:Mule Message: Mule Message is a data that is processed throughout an application via one or more flows. Messages contain mainly two parts: Header: contains metadata about the message. Metadata consists of properties that provide useful information about the message.
A payload in API is the actual data pack that is sent with the GET method in HTTP. It is the crucial information that you submit to the server when you are making an API request. The payload can be sent or received in various formats, including JSON.
– The message payload, which contains your business-specific data. A Mule message is, itself, embedded within a Mule message object. Some Mule message objects may contain variables, attachments, and exception payloads. Contained within the message object, variables represent data about a message.
You can create or update variables in these ways:
- Using the Set Variable component.
- Using a Target Variable from within an operation, such as the Read operation to the File connector or the Store operation to the Database connector.
- Using the Datwave Transform Component (EE-Only).
A "transport barrier" is when your Mule message goes through an endpoint that makes use of a transport (say for example, HTTP endpoints, JMS, TCP, VM, etc). There are two ways of calling flows in Mule: Via an endpoint. Via the Flow-Ref component.
