Optimistic Locking vs Pessimistic Locking With EF Core

☄️ Master the Modular Monolith Architecture: https://bit.ly/3SXlzSt 📌 Accelerate your Clean Architecture skills: https://bit.ly/3PupkOJ 🚀 Support me on Patreon to access the source code:   / milanjovanovic   There are two common approaches to concurrency control Pessimistic locking Optimistic locking Pessimistic locking is acquiring a lock on a set of rows while you perform an update. Very safe. Less performant. Optimistic locking compares the row version we know to the one in the database. If they match, you're allowed to perform the update. If they don't match, you can get an exception. I'll show you how to implement optimistic locking with EF Core in this video.
