Design and Implementation of Distributed Lock Services: Redis, ZooKeeper, and SharkLock
The article explains the principles, requirements, and common implementations of distributed lock services using Redis and ZooKeeper, analyzes their drawbacks, and introduces SharkLock's design choices—including lock metadata, reliability via SharkStore, dead‑lock prevention, safety mechanisms, and Raft‑based consistency—to guide developers in building robust distributed locking solutions.
