In Collibra 2024.05, we launched a new user interface (UI) for Collibra Data Intelligence Platform! You can learn more about this latest UI in the UI overview.
Use the following options to see the documentation in the latest UI or in the previous, classic UI:
What is sample data?
Sample data is a set of randomly collected data from a data source. Depending on your environment, sample data can be displayed for Table, Column, or Data Set assets. The purpose of showing sample data is to provide examples of the data so you know what to expect when you use the asset.
When and where can you see sample data?
You can view sample data for an asset only if the following conditions are met:
- The sample data feature is active.
- You have the required permissions.
- Sample data is available for the asset.
- Depending on the method used, the asset is a Table, Column, or Data Set asset.
Note Currently, you can request sample data via Edge only for Table and Column assets.
If sample data is available, it is displayed in:
| Asset type | If Catalog experience is active, you can see the sample data in: | If Catalog experience is not active, you can see the sample data in: |
|---|---|---|
| Table | Summary tab pane
Sample data tab pane |
Details tab pane Sample data tab pane |
| Column | Summary tab pane
Data profiling tab pane |

Note Currently, you can request sample data via Edge only for Table and Column assets. |

| Asset type | Location of sample data |
|---|---|
| Table |
Sample Data tab Tip Columns show a chart icon next to the column name. Clicking the icon opens the Descriptive Statistics dialog box with metadata and profiling information for the column, if available. |
| Column | Summary tab: Descriptive Statistics section |
| Data Set |
Sample Data tab Note Currently, you can request sample data via Edge only for Table and Column assets. |
Tip
In Table and Data Set assets, you see sample data only for columns for which you have the required permission. If you do not have access, you see the text <sensitive> in the column instead of sample data.
How does Collibra handle sample data?
The way Collibra handles sample data depends on how the assets are added in Collibra and how the sample data is collected:
|
Assets are created by registering a data source via Edge. |
Assets are created by registering a data source via Jobserver. |
Assets are manually added or imported. |
|
|---|---|---|---|
|
Sample data for an asset is uploaded via the Catalog REST API - Profiling. |
The sample data is stored in the Collibra cloud repository. The sample data is displayed to all users with the required permissions. |
The sample data is stored in the Collibra cloud repository. This sample data is also used for data classification via the Data Classification Platform. The sample data is displayed to all users with the required permissions. |

Sample data is collected and stored when the data source is registered via Jobserver. |

Sample data can be manually requested for an asset that is registered via the Edge register data source process. |
The randomly collected sample data is cached on the Edge. The sample data is only displayed to users with the required permissions and if the sample data has been requested. Sample data is not anonymized because having access to the data examples via Edge is based on permissions and the sample data is not stored in Collibra. Note
