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.

  • 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
Example: Validate & Execute
