Snap Type:

Write

Description:

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

ETL Transformations & Data Flow

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

Input & Output

Input: This Snap can have an upstream Snap that can pass a document output view. The input document must contain the keys ReceiptHandle and QueueURL.
Output: The Snap would generate a document that contains the result and the original document

Modes

Ultra pipelines: Works in Ultra Pipelines.
Spark mode: Not supported in Spark mode.

Prerequisites:

Users of the Snap must have the following accesses to be able to use this Snap:

Valid AWS account.
Access Key and Secret Key.
IAM Role access

Limitations and Known Issues

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.

Maximum retries

The maximum number of retry attempts for failed retryable requests.

Example: 2

Default value: 3

Batch size

The number of documents the Snap would batch before processing. The maximum number is 10. Would be ignored if client-side buffering is enabled in the SQS Producer Snap.

Example: 5

Default value: 10

Batch timeout

The maximum time in milliseconds the snap waits before a batch is sent out.

Example: 100

Default value: 200

Max outbound batches in parallel

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).

Example: 4

Default value: 5

Snap execution

Select 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.

Examples

Basic Use Case

The following pipeline describes how the Snap functions as a standalone Snap in a pipeline:

The Snap is configured with the following parameters:
