Error

Error handling is to have a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that might arise while running the Pipeline by choosing one of the options from the When errors occur section under the Views tab.

The options available are:

• Stop Pipeline Execution: Stops the current pipeline execution when an error arises.

• Discard Error Data and Continue: Ignores an error completely, discard that record, and continue with the rest of the records.

• Route Error Data to Error View: Routes the data to an error view of the Snap and then decides what to do with the error.

See Error View in Pipeline in examples to understand the Snap error view settings and error output. For more information on the error view and handling error output in a Pipeline, see Error handling in Pipelines.

Label*

Default Value:Create topic
Example: Create topic

String

None

Specify the unique name of the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your Pipeline.

Region

Default Value:N/A
Example: us-east-1, us-west-1

String/Suggestion

None

Specify the AWS region where an application is implemented. If the region field is empty, then the Snap evaluates the region in the following sequence:

• The Topic Arn or Subscription ARN

• The region of the EC2 instance.

Topic Name*

Default Value:N/A
Example: Topic 1

String

None

Specify the name of the target topic.

Default Value: N/A
Example: displayName

String/Suggestion

None

Choose the attribute name:

• DeliveryPolicy: The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.

• Displayname: The display name to use for a topic with SMS subscriptions.

• FifoTopic: When you select FifoTopic, the topic name should be with the extension .fifo and the Attribute value should be true.

• Policy: The policy that defines the users who can access your topic. By default, only the topic owner can publish or subscribe to the topic.

• KmsMasterkeyId: The ID of an AWS-managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms. For more examples, see KeyId in the AWS Key Management Service API Reference.

Example: tag_Name1

String

Snap Execution

Default Value: Execute only
Example: Validate & Execute

Dropdown list

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.
