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 when 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.

Label*

Default Value: Read
Example: BigTable Read

String

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.

Table*

Default Value: 
Example: employee

String/Expression/Suggestion

Specify the name of the table to execute a read request with the given filters.

Filter Search Criteria

Specify the filters to select the event information.

Filter Type

Default Value: rowKey
Example: rowKey

String/Expression/Suggestion

Provide/suggest the filter type that you want the Snap to use for the filter.

Match Type

Default Value: exact
Example: exact

Select the match type of the filter.

Value

Default Value: N/A
Example: row#employee#13

String/Expression

Enter the value of the filter type that you want the Snap to use for the filter.

Snap Execution

Default Value: Execute
Example: Validate & Execute

Dropdown list

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

• Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, it performs full execution of the Snap (unlimited records) during Pipeline runtime.

• Execute only: Performs complete execution of the Snap during Pipeline execution without generating preview data.

• Disabled: Disables the Snap and all Snaps that are downstream from it.
