SQS Acknowledge

Overview

This Snap deletes the message by receipt handle coming from SQS Consumer when Auto Acknowledge is not enabled in the SQS Consumer Snap.

This Snap extracts receipt handle and queue URL from the input Document, and uses them to delete the corresponding message from the SQS instance.



Prerequisites

  • Valid AWS Account.
  • Access Key and Secret Key.
  • IAM Role access.

Known issues

  • The maximum number of inflight messages per queue are:
    • Standard Queue - 120,000 inflight messages per queue.
    • FIFO queue - 20,000 inflight messages per queue.

Snap views

View Description Examples of upstream and downstream Snaps
Input

This Snap has exactly one document input view.

The input document must contain the keys ReceiptHandle and QueueURL.
Output

This Snap has one document output view.

The Snap would generate a document that contains the result and the original document.
Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

  • Stop Pipeline Execution Stops the current pipeline execution when an error occurs.
  • Discard Error Data and Continue Ignores the error, discards that record, and continues with the remaining records.
  • Route Error Data to Error View Routes the error data to an error view without stopping the Snap execution.

Snap settings

Legend:
  • Expression icon (): Allows using pipeline parameters to set field values dynamically (if enabled). SnapLogic Expressions are not supported. If disabled, you can provide a static value.
  • SnapGPT (): Generates SnapLogic Expressions based on natural language using SnapGPT. Learn more.
  • Suggestion icon (): Populates a list of values dynamically based on your Snap configuration. You can select only one attribute at a time using the icon. Type into the field if it supports a comma-separated list of values.
  • Upload : Uploads files. Learn more.
Learn more about the icons in the Snap settings dialog.
Field / Field set Type Description
Label String

Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline.

Default value: SQS Acknowledge

Example: Acknowledge Messages
Maximum retries Integer/Expression The maximum number of retry attempts for failed retryable requests.

Default value: 3

Example: 2
Warning:
  • If the value is greater than 0, the Snap first downloads the target file into a temporary local file. If any error occurs during the download, the Snap waits for the time specified in the Retry interval and attempts to download the file again from the beginning. When download is successful, the snap streams the data from the temporary file to the downstream Pipeline. All tempohrary local files are deleted when they are no longer needed.
  • Ensure that the local drive has sufficient free disk space to store the temporary local file.
Batch size Integer/Expression

Specify the number of documents the Snap would batch before processing. The maximum number is 10. The Batch size is ignored if you select the Client-side buffering checkbox in the SQS Producer Snap.

Default value: 10

Example: 5
Batch timeout Integer/Expression

Specify the maximum time in milliseconds the Snap must wait before sending out a batch of messages.

Default value: 200

Example: 100
Max outbound batches in parallel Integer/Expression

Specify the maximum number of concurrent batches for each type of outbound request. The greater the number, the greater the throughput that can be achieved (at the expense of consuming more threads).

Default value: 5

Example: 4
Snap execution Dropdown list
Choose one of the three modes in which the Snap executes. Available options are:
  • 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

Default value: Validate & Execute
