An example of an AI chatbot conversation about the limitations of optimistic locking in databases.
What are the limitations of optimistic locking?
Optimistic locking can lead to issues like lost updates, increased transaction retries, and performance bottlenecks under high contention.
Can you explain how lost updates happen?
Lost updates occur when two transactions read the same data and then both try to update it, with the last one overwriting the first.
Are there scenarios where optimistic locking is not recommended?
Yes, it's not recommended in high contention scenarios where many transactions are trying to update the same data simultaneously.
What are some alternatives to optimistic locking?
Alternatives include pessimistic locking, where a transaction locks the data for exclusive access, preventing others from reading or writing.
