What is the difference between database locking and optimistic locking?
Database locking prevents multiple transactions from conflicting by locking resources, while optimistic locking allows transactions to proceed without locks, checking for conflicts before committing.
Can you give me an example of when to use optimistic locking?
Optimistic locking is ideal in scenarios with low contention, like a web application where users rarely edit the same record simultaneously.
What are the downsides of using database locking?
Database locking can lead to deadlocks and reduced performance due to waiting for locks to be released, especially in high-concurrency environments.
How does optimistic locking handle conflicts?
Optimistic locking checks for conflicts at the time of commit. If a conflict is detected, the transaction is rolled back, and the user is notified.
