An example of an AI chatbot conversation about optimistic locking in databases.
What is optimistic locking in database management?
Optimistic locking is a concurrency control method that assumes multiple transactions can complete without affecting each other.
How does it differ from pessimistic locking?
Unlike pessimistic locking, which locks resources to prevent conflicts, optimistic locking allows transactions to proceed without immediate locks.
When should I use optimistic locking?
It's best used in scenarios where conflicts are rare, as it can improve performance by reducing lock contention.
Can you give an example of how it works?
Sure! In optimistic locking, a version number is checked before committing changes. If the version has changed, the transaction fails.
