Sampling data for a running job

You can sample data from a running job. This is useful if you want to inspect the data to make sure the job is running correctly and producing the results you expect.

Sampling the results to your browser allows you to inspect the queried data and iterate on your query. You can sample 100 rows in the Results tab by clicking on the Sample button in the Console. In case you do not add any sink to the SQL job, the results automatically appear in the Results tab.

  1. Select Console on the main menu.
  2. Go to the SQL Jobs tab.
  3. Select the job you want to edit.
  4. Go to the Details tab at the bottom.
  5. Click Edit Selected Job.
    The SQL window in Edit Mode appears.
  6. Click Sample.
Sample results are displayed in the results window. If there is no data meeting the SQL query, sampling stops after a few attempts.
