Making changes

Whenever you make changes to any part of the configuration we do our best to ensure that it is a “safe” change and that you have an option to revert it again.

Concurrent edit protection

Kwanza uses a lamport clock to ensure that the order of updates to any stored entity is preserved and that you cannot overwrite an entity without having seen the latest version beforehand. This translates to the fact that if two people edit the same thing at the same time one of these may get an error saying that their changes cannot be saved as it would overwrite the changes made by the first person. It is a safety feature and it makes editing an item concurrently safe, but it does not make it very easy to do so.

History of changes

All changes are tracked in Kwanza meaning that its possible in Cuesta to see the history of changes made to e.g. a flow, and it is possible to revert to a previous version. For flows this feature can be accessed through the Changelog tab in the flow editor.

For the rest of the items such as users, groups, tables, subject, manufacturers and services the changelog is accessible throug a changelog button on the item’s edit page. The button provides a list of changes, and after selection of the specific change marks the fields which have been changed.
