Introduction to offline computing task historical versions

The offline computing task historical versions page displays the version history and execution information for the current offline computing task. Version information includes version number, modifier, creation time, status, remarks, and supported management operations. Execution information includes type, executor, start time, duration, status, and supported management operations.

Version information
- View version information: Click the icon to navigate to the version details page to view specific information about the task version. This includes basic information, computing code, runtime parameters, scheduling configuration, scheduling dependencies, runtime configuration, and resource configuration.
  If an offline scheduling template is used in the task scheduling configuration, only the name of the offline scheduling template is displayed without detailed configuration information. You can click the template name to navigate to the offline scheduling template page to view detailed scheduling configuration information.
- Compare versions: Click the icon to navigate to the version comparison page. By default, the selected version is compared with the current version of the task. You can switch versions to view differences between various versions, with differences highlighted.
- Roll back to this version: Click the icon to roll back the task to the currently selected version.
  If a computing task of type ADB_PG_SQL, STARROCKS_SQL, DORIS_SQL, SELECTDB_SQL, or GAUSSDB_SQL was created by converting a database SQL task, you can roll it back to a database SQL computing task.
  Important
  The rollback operation cannot be revoked. Please proceed with caution.
