We have an asynchronous task that performs a potentially long-running calculation for an object. The result is then cached on the object. To prevent multiple tasks from repeating the same work, we added locking with an atomic SQL update: UPDATE objects SET locked = 1 WHERE id = 1234 AND locked = 0 The locking is only for the asynchr...
