Request sample data via Edge

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.

Prerequisites

• You have registered a data source via Edge.
  If you want to request sample data from Databricks Unity Catalog or Dataplex Catalog integration, ensure that you have integrated Databricks Unity Catalog or Dataplex Catalog data sources.
• Your Edge or Collibra Cloud site has a sampling capability for that data source.
• You have synchronized one or more schemas of the registered database.
• You have the required permissions to see sample data.

Steps

1. Open the Column or Table asset for which the data source is registered via Edge or open a Data Product or Data Product Port asset that is related to Table or Columns assets for which sample data is available.
   
2. For a column, click Summary, and go to Descriptive Statistics.
   For a table, click Sample Data. For a column, click Data Profiling.
   For a table, click Sample data.
   For a data product or data product port, click Sample Data and select the table for which you want to view the 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.

   Important It can take some time for the sample data to be displayed. Don’t navigate away from the page while the process is ongoing.
   

   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 time because the job is added to a job queue. You can navigate to other assets while the job is in progress.
   As soon as the job is completed, you receive a notification. When you open the asset again, the sample data will be displayed after some time.
   Note 

   • It takes some time to collect the sample data. You can navigate to other assets while the request is in progress.
   • Requested sample data via Edge only remains available on the Edge cache for a limited time.
