3.8 Locking with Valid Time Support

If a row in a version-enabled table with valid time support is locked, it is automatically locked for its entire valid time period. There is no way to lock a row for a specified time period.

Any updates in a pessimistically locked workspace will lock the rows seen from an ancestor workspace as the updates are performed in the workspace. The locked rows in ancestor workspaces will not be further updatable in their valid time periods as long as they are locked.
