RabbitMQ Acknowledge
RabbitMQ Acknowledge
Jun 13, 2024

Snap type:
Read
Description:
This Snap performs an acknowledge, reject or a recover action on the received message from the Rabbitmq server via the RabbitMQ Consumer used in the upstream. The Snap should always be used in conjunction with the RabbitMQ Consumer Snap within a pipeline. The RabbitMQ Consumer Snap should have the Acknowledgement mode set to PIPELINE_CONTROL.
ETL Transformations & Data Flow
The Snap extracts the delivery tag from the the Consumer and performs selected acknowledge function. On the RabbitMQ Consumer Snap, select thePIPELINE_CONTROL option when using the RabbitMQ Acknowledge Snap in a pipeline.
The RabbitMQ Consumer Snap writes the messages to the output view along with headers containing a delivery tag which is then forwarded to the RabbitMQ Acknowledge Snap.
The RabbitMQ Acknowledge Snap may be positioned anywhere in the pipeline following the Consumer Snap. The RabbitMQ Acknowledge Snap should be configured with necessary acknowledgement mode based on the message processing.
Input & Output
Input: This Snap optionally accepts the delivery tag of the RabbitMQ message consumed by the Consumer Snap upstream.
Output:
This Snap writes the delivery tag received to output view if present. Errors can be routed to the error view if enabled or otherwise cause the Snap to fail during execution.
Privileges to perform various actions on the Queues such as receive and send messages.
Limitations and Known Issues:
When using the RabbitMQ Acknowledge Snap, the pipeline can be configured with a single RabbitMQ Consumer Snap only (more than one RabbitMQ Consumer Snaps cannot be configured within the same pipeline).
The pipelines cannot be validated if a child pipeline contains either a RabbitMQ Acknowledge Snap or a Consumer Snap within it.
When configuring with the Acknowledge Snap, since the message processing is sequential, a single message only will be processed at a time in the pipeline and second message is processed only when the current message is either acknowledged or recovered or rejected.
Configurations:
This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See RabbitMQ Account for information on setting up this type of account.
Views
Input
This Snap has exactly one document input view.
Output
This Snap has at most document output view.
Error
This Snap has at most one document error view and produces zero or more documents in the view.
Troubleshooting:
The section describes typical issues you may encounter while using this Snap, and instructions on how to workaround them:
Settings
Label
Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.
Acknowledge type
Required. Specifies the appropriate acknowledge type of the message to be performed. The message type options available are: Acknowledge, Reject and Recover.
On the RabbitMQ Consumer Snap, select the PIPELINE_CONTROL option when using the RabbitMQ Acknowledge Snap within a pipeline.
Acknowledge Message: The Consumer performs a successful acknowledgement of the message to the RabbitMQ server and removes that message from the queue.
Reject Message: The Consumer notifies the RabbitMQ server to mark the particular message as ‘dead lettered’ and route the message to the ‘Dead Lettered Exchange’. However if the ‘Dead Lettered Exchange’ is not configured on the RabbitMQ server, the message would be dropped from the queue automatically.
Recover Message: The Consumer notifies the RabbitMQ server to re-queue the message to be available in the next read.
Default value: Acknowledge Message
Snap Execution
Select one of the following three modes in which the Snap executes:
Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.
Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
Disabled: Disables the Snap and all Snaps that are downstream from it.
Default Value: Execute only Example: Validate & Execute
Examples
RabbitMQ Acknowledge Snap performs a basic acknowledge function
The pipeline reads the delivery tag from the RabbitMQ Consumer Snap and forwards it to the Acknowledge Snap for an appropriate acknowledge operation.
The RabbitMQ Consumer Snap is set with the PIPELINE_CONTROL option as a Message Acknowledge Mode:
The delivery tag as passed using the Mapper Snap:
The Acknowledge Snap with Acknowledge type as Acknowledge Message performs a successful acknowledgement on pipeline execution:
RabbitMQ Acknowledge Snap performing multiple modes of message acknowledgement
In the below pipeline, the received messages from the RabbitMQ server are consumed and acknowledged as configured.
The pipeline is configured to perform:
an acknowledgement of the message
re-queue the recovered message
reject the message and route it to the Dead lettered queue.
Enhanced the RabbitMQ Consumer Snap with the Execution timeout field that enables the Snap to gracefully stop within the specified time, even if the message count threshold is not met. If the message consumption occurs before timeout then the snap will consume the message and stops gracefully before timeout as expected.
