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*

String

N/A

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.

Default Value: N/A
Example: DeleteTopic

Region

String

N/A

Specify the AWS region where the application is implemented. Alternatively, click the Suggestion icon to fetch a list of Region. If the region field is empty, then the Snap evaluates the region in the following sequence:
Topic Arn or Subscription ARN > the region of the EC2 instance.

Default value: None
Example: us-east-1, us-west-1

Topic Arn

String

N/A

Specify the Amazon Resource Name (ARN) of the topic. This is a suggestible field and suggestions will be populated based on the Account settings.

Default Value: N/A
Example: Topic 1

Subscribe Arn*

String

N/A

Specify the ARN of the subscription you want to delete.

Default Value: N/A
Example: Subscription 1

Snap Execution

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.
