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. The available options are:

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

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the rest of the records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Label*

Default Value: Avro Formatter
Example: Avro_Formatter

String

Specify 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.

Schema File*

Default Value: [None]
Example: sldb:///foo/bar/schema.avsc

String/Expression

Specify the path to the schema file in .avsc format

Checkbox

Select the checkbox to specify an action that the Snap must take if the input view contains empty documents. If selected, the Snap does not write anything to the output if no documents are received in the input. Else, the Snap writes an empty array in the output view if no documents are received in the input view. 

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.
