| Each row tracks the version at which it was last modified. | ||
| When a row is created, `last_updated_at_version` equals `created_at_version`. | ||
| When a row is updated, a new row is created with both `created_at_version` and `last_updated_at_version` set to the current version, and the old row is marked deleted. |

Seems like the old row only marked deleted, not modify the last_updated_at_version?

yes, if we enable the stable row ID feature, when updating, the old row is only marked deleted, and the last_updated_at_version will be tracked in the new fragment for the same row id.
