The version management feature allows you to roll a job back to a historical version.
On the Development & Testing page, click Manage version to view all published versions of the current job in the side pop-up window. Here, you can click a version to view job details in this version, but the version is not editable. In the Manage version pop-up window, you can delete unnecessary versions or compare versions to identify their differences in code and configurations.
Changing the job version
To change a job to a published version, you need to stop its online running version first, and then click Run version to run the target version. You need to select a running policy based on the job status, without entering the version description, and then click Confirm.
Comparing versions
You can compare versions to identify their differences and select a version to run. The version comparison feature enables you to compare the SQL code and configurations in different versions of a SQL job.
In the Manage version pop-up window, select a version as the initial version, and click Compare.
In the Compare versions pop-up window, view the code of the initial version. Select a version on the left to compare it with the current (initial) version.
The code differences are highlighted for easy view.
Click Configuration to view configuration differences of the versions.
Deleting a version
In the Manage version pop-up window, click Delete for the target version to delete it (unable to delete a running version).
