How to implement Distributed Locks with Redis

For the single-process concurrency scenario, you can use the lock provided by the programming language and the corresponding class library, such as the Synchronized syntax and the ReentrantLock class in Java, to avoid concurrency problems.

If in a distributed scenario, implements the simultaneous access of code and resources by threads of different clients, guarantees the security of processing shared data under multithreading, then needs Use distributed lock technology.

Distributed lock is a lock implementation that controls distributed systems or different systems to access shared resources. If a resource is shared between different systems or different hosts in the same system , Mutual exclusion is often required to prevent interference with each other to ensure consistency.
