What are some alternatives to optimistic concurrency control?
Some alternatives include pessimistic concurrency control, timestamp ordering, and multi-version concurrency control.
Can you explain pessimistic concurrency control?
Pessimistic concurrency control locks resources to prevent conflicts, ensuring that only one transaction can access a resource at a time.
What are the pros and cons of using timestamp ordering?
Timestamp ordering allows transactions to be executed based on their timestamps, which can reduce conflicts but may lead to increased complexity.
How does multi-version concurrency control work?
Multi-version concurrency control keeps multiple versions of data, allowing transactions to read old versions while new ones are being written.
