The Architecture of Microservice Transaction Based on Distributed Consensus with Kubernetes
summary
Claims that a Paxos-based atomic commit replaces fragile Sagas and single-coordinator two‑phase commit by using distributed consensus for transaction termination, implemented as redundant coordinators in Kubernetes. Prototype wires a transaction-aware JDBC driver to per-service resource managers and a consensus-backed coordinator cluster, persists prepare/commit state, and prevents write‑write conflicts and heuristic hazards. It works functionally in tests, trading higher commit latency and extra messaging for near‑100% availability and stronger consistency.
