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 while running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab:

  • Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error.

  • 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.

Learn more about Error handling in Pipelines.

Snap Settings

  • Asterisk ( * ): Indicates a mandatory field.

  • Suggestion icon (): Indicates a list that is dynamically populated based on the configuration.

  • Expression icon ( ): Indicates the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.

String

Specify a unique name for the Snap. Modify this to be more specific, especially if you have more than one Snap of the same type in your Pipeline.

 

Project ID

Default Value: N/A
Example: Test-project-324543

Detailed Information

Default value: Deselected

Checkbox

Select this checkbox to enable the Snap to access additional fields for displaying them in the output. The additinal fields include: Dataset Location, Dataset Description, Dataset Creation Time, Dataset Last Modified Time, and Dataset Default Table Expiration.

Snap Execution

Default Value: Execute only
Example: Validate & Execute

Dropdown list

Select one of the following three modes in which the Snap executes. Options include:

  • 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.

Example

Deleting Dataset from BigQuery

This example Pipeline demonstrates how to delete a dataset from BigQuery.

First, configure the BigQuery Dataset Create Snap as highlighted in the image.

On validation, the BigQuery Dataset Create Snap creates a babynames_cd dataset in the case16370 Project ID.

Next, configure the BigQuery Dataset Delete Snap to delete the babynames_cd dataset that belongs to the case16370 Project ID.

On validation, the Snap deletes the content and displays the details of the deleted dataset and project.
