Mapper

This Snap exposes the avsc schema in its input view. You must use a Mapper Snap in front of this Snap to map the fields present in .avsc schema file.

Output

Document

Min: 1
Max: 1

Binary

Any serialized binary stream output processing Snap that contains data and its schema.

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.

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 whether the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.

Field Name	Type	Description
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
Ignore empty stream Default value: Deselected Example: Selected	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.
Snap Execution Default value: Validate & Execute Example: Disabled	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.
