What are some real-world use cases of distributed locks?

Distributed locks are used in various scenarios, such as coordinating access to shared resources in microservices, ensuring data consistency in databases, and managing distributed systems where multiple processes need to access the same resource without conflicts.

Can you give me an example of how they work in microservices?

Sure! In a microservices architecture, if multiple services need to update a shared database, a distributed lock can ensure that only one service can perform the update at a time, preventing race conditions and ensuring data integrity.

What technologies are commonly used to implement distributed locks?

Common technologies include Redis, Zookeeper, and etcd. These tools provide mechanisms to create and manage distributed locks effectively.

Are there any drawbacks to using distributed locks?

Yes, some drawbacks include potential performance bottlenecks, increased complexity, and the risk of deadlocks if not managed properly.
