Description

①Summary

This section displays information about the table, such as its type, environment, name, tags, and description. You can also perform the following operations:

• Search for other asset objects: Quickly search for and view the details of other assets.

• View asset details: If the object is listed in the Asset Catalog, you can go to the catalog details page to view its listing information.

• View production/development object: Quickly switch to the details page for the object in the corresponding production or development environment.

• Tag: Displays the tag values configured for the asset. To modify tags, click Edit:

  • The length of each tag value cannot exceed 128 characters.

  • Each asset object can have up to 20 tag values.

  • Super administrators can modify asset tags for all table types. The current table owner can modify asset tags for tables they own. Project administrators can modify asset tags for real-time metatables in the projects they manage.

• Favorite: Click to add or remove an asset from your favorites. After you favorite an asset, you can view the 30 most recently favorited assets under Asset Checklist-My Footprints for easy retrieval. You can also view all your favorited assets in the Personal Data Center. For more information, see View and manage my favorited assets.

• Report a quality issue: Use this feature to report quality issues to the quality owner. Examples include unstable data output or inaccurate data content. The owner is then notified to make corrections, which helps improve asset availability and health. For configuration details, see Add and manage a problem checklist.

  You must enable the Data Quality module to use this feature. You can then track the status and resolution of reported issues in the problem checklist within the Data Quality module.

• View DDL Statement: Click to view the Flink DDL statement for the current data table in the tenant's compute engine. Additionally, you can select a Data Source Type and click Generate DDL Statement. The system generates a DDL statement to create a table with the same structure as the current table in the specified type of data source. If you select Automatically Add Escape Characters, the generated DDL statement automatically includes the corresponding escape characters for the selected source type. This helps prevent issues such as system keywords being misinterpreted.
