ZooKeeper
An Apache open-source distributed coordination service that provides distributed configuration management, naming services, and cluster management. It is widely used in distributed systems for node health monitoring and metadata management.
Timeline (last 90 days)
Coordination services such as Redis, ZooKeeper, and etcd all provide lease-related primitives.
Reproducing single-instance consistency guarantees in an open-source implementation requires solving the problem of single-instance leader election across nodes, which typically relies on distributed coordination services such as etcd or ZooKeeper.
Strongly consistent coordination services such as ZooKeeper are often used as the control plane for Chain Replication systems, responsible for maintaining chain membership views, coordinating node joins and departures, and triggering chain reconstruction.
The solution of reusing database transaction locks eliminates the need to additionally introduce distributed lock middleware such as Redis or ZooKeeper.
脑裂问题可通过引入仲裁节点（quorum）、STONITH 机制或基于 Raft/Paxos 共识算法的协调服务（如 etcd、ZooKeeper）来解决
Kafka 3.x 引入的 KRaft 模式移除了 ZooKeeper 依赖
