Request sample data

If a data source is registered via Edge, no sample data is available by default. It means you may need to request the sample data. The requested sample data only remains available via Edge for a limited amount of time.

Steps

1. Open the Column or Table asset for which the data source is registered via Edge.
2. For a column, click Data Profiling.
   For a table, click Sample data.
   Collibra performs checks to determine what happens in the page.
   If sample data is available in the Edge cache for this data source, the sample data is displayed.

   Note It can take some time for the sample data to be displayed.
   

   If no sample data is available in the Edge cache and if you have the required permissions to see sample data, the Request Sample Data button is displayed.

3. If displayed, click the Request Sample Data button or go to Actions -> Request Sample Data.
   A 'Request sample data' job starts. This job collects and caches the sample data on the Edge site.
   Collecting and caching the sample data can take some time. You can navigate to other assets while the request is pending.
   As soon as the request is completed, you receive a notification. When you open the asset again, the sample data will be displayed after some time.

   Note Requested sample data via Edge only remains available on the Edge site for a limited time. Once a day, Edge deletes all the data that is older than 24 hours. Once the cached data is deleted, you will need to request the sample data again.
