Introduction

A RabbitMQ Publish activity publishes a message to a RabbitMQ endpoint and is intended to be used as a target to consume data in an operation. After configuring a RabbitMQ connection, you can configure as many RabbitMQ activities as you like for each RabbitMQ connection.

Creating a RabbitMQ Activity

From the design canvas, open the Connectivity tab of the design component palette:

Connectivity tab

Use the Show dropdown to filter on Endpoints, and then click the RabbitMQ connection block to display activities that are available to be used with a RabbitMQ connection:

RabbitMQ activities

To create an activity that can be configured, drag the activity block from the palette to the operation.

For more information about the parts of an operation and adding activities to operations, see Operation Creation and Configuration.

Configuring a RabbitMQ Publish Activity

Follow these steps to configure a RabbitMQ Publish activity:

Step 1: Enter a Name and Specify Settings

RabbitMQ Publish Activity Configuration Step 1

TIP: Fields with a variable icon Variable icon support using global variables, project variables, and Jitterbit variables. Begin either by typing an open square bracket [ into the field or by clicking the variable icon to display a list of the existing variables to choose from.

  • Name: Enter a name to use to identify the RabbitMQ Publish activity. The name must be unique for each RabbitMQ Publish activity and must not contain forward slashes (/) or colons (:).

  • Exchange: Enter the exchange name.

  • Routing Key: Enter the routing key.

  • Save & Exit: If enabled, click to save the configuration for this step and close the activity configuration.

  • Next: Click to temporarily store the configuration for this step and continue to the next step. The configuration will not be saved until you click the Finished button on the last step.

  • Discard Changes: After making changes, click to close the configuration without saving changes made to any step. A message asks you to confirm that you want to discard changes.

Step 2: Review the Data Schema

RabbitMQ Publish Activity Configuration Step 2

  • Data Schema: The request data schema for RabbitMQ is displayed. If the operation uses a transformation, the data schema is displayed again later during the transformation mapping process, where you can map to target fields using source objects, scripts, variables, custom values, and more.

    The RabbitMQ connector uses the RabbitMQ Java Client v5.8.0. Refer to the RabbitMQ documentation for information on the schema fields.

  • Refresh: Click the refresh icon Refresh icon or the word Refresh to regenerate schemas from the endpoint. This action also regenerates the schema in other locations throughout the project where the same schema is referenced, such as in an adjacent transformation.

  • Back: Click to temporarily store the configuration for this step and return to the previous step.

  • Finished: Click to save the configuration for all steps and close the activity configuration.

  • Discard Changes: After making changes, click to close the configuration without saving changes made to any step. A message asks you to confirm that you want to discard changes.

Next Steps

After configuring a RabbitMQ Publish activity, complete the configuration of the operation by adding and configuring other activities, transformations, or scripts as operation steps. You can also configure an operation's operation settings, which include the ability to chain operations together that are in the same or different workflows.

After a RabbitMQ activity has been created, menu actions for that activity are accessible from the project pane in either the Workflows or the Components tabs, and from the design canvas. See Activity Actions Menu for details.

RabbitMQ Publish activities can be used as a target with these operation patterns:

Other patterns are not valid using RabbitMQ Publish activities. See the validation patterns on the Operation Validity page.

A typical use case is to use a RabbitMQ Publish activity in the Two-Transformation Pattern. In this example, the first transformation (RabbitMQ Publish Request) creates a request structure that is passed to the RabbitMQ Publish activity. The second transformation (RabbitMQ Publish Response) receives the response structure, which is then written to a variable by a Variable Write activity (Write RabbitMQ Publish Response) and a message is then logged by the Write to Operation Log script:

RabbitMQ Publish operation

To use the activity with scripting functions, write the data to a temporary location and then use that temporary location in the scripting function.

When ready, deploy and run the operation and validate behavior by checking the operation logs.
