Snap Execution

Drop-down list

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

Validate & Execute. Performs limited execution of the Snap and generates a data preview during Pipeline validation, then 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 downstream from it.

Execute only

Examples

Obtain Employee Details

This example demonstrates the process to retrieve employee details from Employee Data Set table using Adobe Experience Execute Snap. Use Mapper Snap to transform incoming data and send the output to JSON Formatter Snap to read the document and write the JSON binary data to output. Finally, use File Write Snap to write JSON file output to an end point.

In this example, we will execute a SQL query to retrieve employee data through Adobe Experience Execute Snap.

First, provide inputs to the Adobe Experience Platform Execute Snap Settings fields. You will retrieve the data on the basis of the given SQL Statement on running the Pipeline.

Now, we connect Mapper Snap to transform incoming data for mapping and transfer the output to JSON Formatter Snap.

In the next step, we connect JSON Formatter Snap to read JSON document data from Mapper Snap, and formats and writes it as JSON binary data to its output view.

Finally, we connect File Writer Snap to the Pipeline to write JSON file output to an end point. Enter a name in the File name field and run the Pipeline. You will find a JSON file with a record of employee details.
