Overview
Etlworks automatically tracks changes for all artifacts: Connections, Formats, Listeners, Flows, Macros, Schedules and Agents. Thus, there is nothing to configure except the retention policy.
Version control is supported for the following artifacts: Flows, Connections, Formats, Listeners, Schedules, and Macros and Agents.
Using built-in version control, you can:
- View the history of changes or who-changed-what-and-when
- Compare any two versions
- Revert to any previous version
- Add comments to the commit when saving the artifacts

Configure the retention policy
By default, Etlworks only keeps the last 20 modifications to any artifact. Older changes are purged once a day by the scheduled maintenance task. This parameter can be changed.
Important: Only customers on the dedicated instance (including self-hosted) can configure the retention policy.
Go to Settings, click Maintenance, and then select Clean history records.
You can change the following options:
- Enabled flag: if this maintenance task is disabled, Etlworks will keep the history of changes forever. The default would be enabled.
- Schedule: is how often you want the system to run a maintenance task. The default is once a day.
- Keep # of history records: is the number of history records you want to keep. The default is 20.
- Remove deleted: If this option is enabled, the system will remove the history records for the deleted artifacts. The default choice is enabled.
- Keep deleted in the past N days: This is the number of days where the history records for the deleted artifacts are kept. The default is 30.
