Metadata change record

Prerequisites

To configure metadata change records for computing source tables, you must purchase either the Intelligent R&D Edition or the Asset Operation Pro.

Permission description

Super administrators and system administrators have the authority to configure metadata change records for both computing and data source tables.

Precautions

• After enabling metadata changes, you can view the historical versions of each object in the object details under Administration > Metadata > Metadata Checklist. Additionally, you can configure the display of metadata change records for individual objects on the table asset editing page that requires manual entry.

• Changing the metadata change record from enabled status to shutdown status will result in the system disabling metadata changes and deleting all historical versions, except for the most recent one.

• If you alter the saving scope of the source table from all tables to production environment tables, the system will automatically remove the corresponding development environment tables, preserving only the latest metadata change record for the production environment.

Metadata change record configuration

1. On the Dataphin homepage, from the top menu bar, select Administration > Metadata.

2. In the left-side navigation pane, select General Configuration > Metadata Change Record. On the Metadata Change Record page, you can click the Edit button at the bottom to enable or disable metadata changes for the source table.

   • Computing Source Table Configuration: By default, this is disabled. Once enabled, you can configure the scope and the number of metadata change record versions to save.

     • Saving Scope: The default setting is Production Environment Tables. You can switch to All Tables.

     • Number Of Saved Versions: By default, the system saves the last two versions of change records. You can adjust the number of saved versions to any integer from 2 to 5.

   • Data Source Table Configuration is disabled by default. Once enabled, you can configure the scope and the number of metadata change record versions to save.

     • Saving Scope: The default setting is All Tables. You can switch to Production Environment Tables.

     • Number Of Saved Versions: By default, the system saves the last 2 versions of change records. You can adjust the number of saved versions within a range of 2 to 5 versions.

3. Click OK to finalize the configuration of the metadata change record.
