How do you choose between optimistic and pessimistic locking in distributed systems?
Locking is a common technique to ensure consistency and prevent conflicts in distributed systems, where multiple nodes or processes may access or modify shared data. However, choosing the right locking strategy can be challenging, as different approaches have different trade-offs in terms of performance, scalability, availability, and complexity. In this article, we will compare two popular locking strategies: optimistic and pessimistic locking, and discuss how to decide which one suits your system better.
