File System

The Data Generator produces arbitrary data.

The data is written to files on File System by Write File. The files are stored in the directory ./tmp/demo/ (where ./ is the current working directory, i.e. where the Data Pipeline Engine was started). The file names follow the scheme file_<counter>.txt.

The Read File reads this file and the content is written to a terminal.

Configure and Run the Graph

Follow the steps below to run the example from the Data Pipeline UI:
  1. In the left panel, select the Graphs tab and navigate to com/sap/demo/file.
  2. In the tool bar, select Run (play button).
  3. The Status panel indicates if the graph is running.
  4. Use the context menu Open UI of the Terminal node to open the terminal.
  5. The terminal opens and you see the produced files and their content.
