What are some use cases for optimistic locking in databases?

Optimistic locking is useful in scenarios where conflicts are rare. Common use cases include collaborative applications, e-commerce platforms, and any system where multiple users might update the same data.

Can you explain how optimistic locking works?

Sure! Optimistic locking allows multiple transactions to proceed without locking the data. When a transaction is ready to commit, it checks if the data has been modified since it was read. If not, it commits; if yes, it rolls back.

What are the advantages of using optimistic locking?

The main advantages include improved performance in low-contention scenarios, reduced locking overhead, and better user experience since users can work concurrently without waiting.

Are there any drawbacks to optimistic locking?

Yes, the main drawback is that it can lead to increased rollbacks in high-contention scenarios, which may affect performance. It's essential to assess the application's specific needs.
