Summary information

Displays information such as the type, environment, name, tag, and description of the table. You can also perform the following operations:

  • Search other asset objects: You can quickly search and switch to view details of other assets.

  • View Asset Details: If the current object is listed in the Asset folder, you can quickly jump to the folder product page to view the listed information.

  • View Production/development Objects: Supports quick switching to the object details of the current object in the corresponding production/development environment.

  • Tag: Displays the configured tag value of the current asset. To modify the tag, you can click Edit:

    • The length of each tag value does not exceed 128 characters.

    • Each asset object can be configured with up to 20 tag values.

    • The super administrator can modify the asset tags of all table types. The current table owner can modify the asset tags of the tables they are responsible for. The project administrator can modify the asset tags of real-time meta tables under the projects they are responsible for.

  • Favorite: Click to add to or remove from favorites. After adding to favorites, you can view the 30 most recently favorited assets in Asset checklist - My Footprint for easy subsequent queries. You can also view all favorited assets in the Personal Data Center. For more information, see the referenced document.

  • Feedback quality issues: You can use this feature to report quality issues encountered during the use of assets (such as unstable data output or inaccurate data content) to the current quality owner, notifying the relevant owner to make timely corrections, thereby promoting the improvement of asset availability and health. For configuration details, see the referenced document.

    You need to activate the Data Quality module to use the feedback quality issues feature. Subsequently, you can view the processing flow and results of the feedback issues in the checklist of the quality module.

  • View DDL Statement: Click to view the corresponding Flink Data Definition Language (DDL) statement of the current data table in the tenant compute engine. Additionally, you can select the Data Source Type and click Generate DDL Statement. The system will generate a table DDL statement with the same structure as the current table in the specified type of data source system. If you select Automatically Add Escape Characters, the generated DDL statement will automatically add the corresponding escape characters based on the selected source type, reducing issues such as incorrect escape of system keywords.

At the same time, you can click the Actions column's data lineage image icon to view the field lineage centered on the specified field.

Lineage

Displays the data lineage between tables. The lineage sources include integrated sync tasks, custom lineage compute tasks, and SQL compute tasks and logical table tasks that the system can automatically parse. For more information, see Table-level lineage.

Note

The system parses the data lineage of tables in the development environment when the task is submitted. It parses the data lineage of tables in the production environment when the task is published. Parsing supports up to 100,000 lineage relationships for a single task submission or publication. If exceeded, it will not be recorded and cannot be displayed in the asset folder.
