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.
