The Lock status is a particular state for all items of your Talend projects. Locks are to be used to prevent edition conflicts as different users can possibly work on the same data quality item.

How to lock/unlock items

In the default mode, when you first open a data quality item in the DQ Repository tree view, you get the edition privilege and a lock is docked on the item icon in the tree view.

Until you release the lock by closing the item you are editing, other users will not be able to make any change on it. The item will show with a red lock in their DQ Repository tree views.

You can decide to lock or unlock any of the items listed in your DQ Repository tree view without having to open the item or closing it. To do so:

  • Right-click the item and select Lock element or Unlock element.

You will not have access to the Lock element or Unlock element options if the item is open in the studio.

All other users will have a read-only access for locked items until they are unlocked.

A locked item can only be unlocked by the lock owner.

How to access locked items (default)

On the DQ Repository tree view, the red lock appended to the data quality item shows that the item is already being edited by another user.

But you can still open and view the locked item in a read-only mode:

  • Right-click the locked item in the DQ Repository tree view, and then click Open to view the item content.
