Optimistic Locking
A concurrency control approach that allows multiple users to check out the same item simultaneously, detecting and resolving conflicts at check-in rather than preventing them at check-out.
Why it matters
Optimistic locking enables parallel work on the same item across sites, at the cost of explicit conflict resolution when two users modify the same data simultaneously.
