RabbitMQ Acknowledge activity¶
Introduction¶
A RabbitMQ Acknowledge activity, using its RabbitMQ connection, acknowledges a message (using an ackId
) in RabbitMQ and is intended to be used as a target to consume data in an operation.
Create a RabbitMQ Acknowledge activity¶
An instance of a RabbitMQ Acknowledge activity is created from a RabbitMQ connection using its Acknowledge activity type.
To create an instance of an activity, drag the activity type to the design canvas or copy the activity type and paste it on the design canvas. For details, see Create an activity instance in Component reuse.
An existing RabbitMQ Acknowledge activity can be edited from these locations:
- The design canvas (see Component actions menu in Design canvas).
- The project pane's Components tab (see Component actions menu in Project pane Components tab).
Configure a RabbitMQ Acknowledge activity¶
Follow these steps to configure a RabbitMQ Acknowledge activity:
-
Step 1: Enter a name and ack multiple messages
Provide a name for the activity. -
Step 2: Review the data schemas
Any request or response schemas are displayed.
Step 1: Enter a name and ack multiple messages¶
In this step, provide a name for the activity. Each user interface element of this step is described below.
-
Name: Enter a name to identify the activity. The name must be unique for each RabbitMQ Acknowledge activity and must not contain forward slashes
/
or colons:
. -
Ack Multiple Messages: Select to acknowledge multiple messages. This option is overridden by data provided in the multiple field in the activity's request schema.
-
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 schemas¶
Any request or response schemas are displayed. Each user interface element of this step is described below.
-
Data Schemas: These data schemas are inherited by adjacent transformations and are displayed again during transformation mapping.
The RabbitMQ connector uses the RabbitMQ Java Client v5.8.0. Refer to the API documentation for information on the schema nodes and fields.
The Acknowledge activity uses JSON in both its request and response schemas.
-
Refresh: Click the refresh icon or the word Refresh to regenerate schemas from the RabbitMQ endpoint. This action also regenerates a 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 Acknowledge activity, complete the configuration of the operation by adding and configuring other activities, transformations, or scripts as operation steps. You can also configure the operation settings, which include the ability to chain operations together that are in the same or different workflows.
Menu actions for an activity are accessible from the project pane and the design canvas. For details, see Activity actions menu in Connector basics.
RabbitMQ Acknowledge activities can be used as a target with these operation patterns:
- Transformation pattern
- Two-transformation pattern (as the first or second target)
Note
An Acknowledge activity cannot be present in an operation chain that contains both a Consume activity and a Get or Get Bulk activity. Under such circumstances, the operation with the Acknowledge activity becomes invalid.
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.
