This article explains the fundamentals of distributed transactions, including ACID properties, consistency models, sharding strategies, and the two‑phase, three‑phase, and TCC protocols, while discussing CAP and BASE theories and the challenges of implementing reliable distributed databases.
This article explains the fundamentals of distributed transactions, covering ACID, CAP and BASE theories, and reviews various consistency solutions such as two‑phase commit, three‑phase commit, TCC, local message tables, MQ approaches and the Seata framework, highlighting their advantages and drawbacks.
This article explains the fundamentals of distributed transactions, the ACID properties, various consistency models, database sharding strategies, and the two‑phase, three‑phase, and TCC commit protocols, while also discussing CAP, BASE, and practical challenges in large‑scale systems.
This article explains the core principles and a range of consistency protocols—including CAP, ACID, BASE, 2PC, 3PC, Paxos, Raft, Gossip, NWR, Quorum, and Lease—detailing their roles, mechanisms, trade‑offs, and typical use cases in distributed systems.
This article examines why ZooKeeper may not be the optimal solution for service discovery, analyzing CAP trade‑offs, consistency versus availability, scalability limits, health‑check design, and practical lessons from Alibaba’s decade‑long experience to guide the design of robust registration centers.
The article analyzes the limitations of using ZooKeeper for service discovery, compares it with Alibaba's ConfigServer, discusses CAP trade‑offs, scalability, health‑check design, disaster recovery, and provides practical guidance on when to choose alternative registration solutions.
This article uses the story of Tai Chi from the novel *The Heaven Sword and Dragon Saber* to explain the CAP theorem, ACID properties, BASE theory, and two‑phase commit in distributed systems, illustrating how consistency, availability, and partition tolerance correspond to the hard and soft aspects of Tai Chi.
The article analyzes HBase's CP‑oriented CAP limitations, proposes native AP support via Replica, decouples WAL IO to Kafka, optimizes MTTR, introduces multi‑datacenter active/active disaster recovery, and redesigns client write paths and LogSplit processing for higher availability and throughput.
Based on a decade of Alibaba’s production experience, this article analyzes the requirements and design trade‑offs of service‑discovery registries, arguing that ZooKeeper’s strong consistency and coordination focus make it unsuitable as a primary registration center and proposing AP‑oriented, scalable alternatives.
The article offers a comprehensive overview of backend development, explaining core system design principles, architectural patterns, network communication techniques, fault handling strategies, monitoring and alerting practices, service governance mechanisms, testing methodologies, and deployment workflows, from high cohesion and scaling to gray‑scale releases and rollbacks.
This article explains the fundamentals of database transactions, the ACID properties, the challenges of distributed transactions, and compares various solutions such as 2PC, TCC, local message tables, MQ transactions, and Saga, helping readers choose appropriate approaches based on consistency and availability requirements.
