The article explains why a single order operation can involve multiple services and databases, introduces the challenges of distributed transactions, and compares three common solutions—Two‑Phase Commit, TCC, and Saga—detailing their mechanisms, strengths, weaknesses, and suitable scenarios.
This article analyzes common distributed‑transaction scenarios, explains the CAP theorem’s relevance, compares ACID/BASE, TCC, XA, 2PC/3PC, Saga and AT patterns, and provides a decision‑making framework to help architects select the most suitable approach for their microservice systems.
This article explains the fundamentals of distributed transactions, compares classic solutions such as XA, Saga, TCC, local message tables, and transaction messages, and presents a sub‑transaction barrier technique that gracefully handles idempotency, empty rollbacks, and hanging issues in microservice architectures.
This article introduces the fundamental concepts of distributed transactions, explains ACID and BASE properties, and systematically presents classic solutions such as two‑phase commit, SAGA, TCC, local message tables, transaction messages, maximum‑effort notifications, and sub‑transaction barriers for reliable microservice architectures.
