生态 微众银行全国首个分布式银行核心 —— 金融级生产实证
- 一句话
- 微众银行基于 TDSQL 建成全国首个分布式银行核心系统(Openhive,同城多活):单日峰值 14 亿笔交易、可用率 99.999%、单账户年 IT 成本降至 2 元。WeBank built China's first distributed bank core on TDSQL (Openhive, active-active across the same city): 1.4 billion transactions on peak days, 99.999% availability, per-account annual IT cost down to ¥2.
- 窄场景
- 银行/金融核心系统去 IOE:要求同城多活、金融级可用性,且需要"国内已有银行跑在前面"的合规与审计说服力。Bank/finance core systems going off IOE: same-city active-active, financial-grade availability, plus the compliance and audit persuasiveness of "a domestic bank already runs ahead of you".
- 机制
- TDSQL(腾讯分布式数据库,MySQL 协议兼容)支撑微众银行全行系统跑在分布式架构上:同城多活部署、分布式事务、自动容灾切换。"单账户年 IT 成本 2 元"是对比传统"小型机+Oracle+EMC"集中式架构的成本叙事——去 IOE 的经济账。TDSQL (Tencent's distributed database, MySQL-protocol-compatible) runs WeBank's entire estate on a distributed architecture: same-city active-active deployment, distributed transactions, automatic failover. The "¥2 per account per year" is a cost narrative against the traditional "minicomputer + Oracle + EMC" centralized stack — the de-IOE economics.
- 生产验证
- 新浪财经转述"子弹财经"报道的微众银行案例量化数字(https://finance.sina.cn/2025-12-14/detail-inhauqsz3153445.d.html)。诚实标注:独立媒体转述,非腾讯官方直发;数字未独立复现。反差本身也是信息:TDSQL 的用户是"签了合同的银行",不是"写博客的工程师"——社区一线工程师的生产分享本次几乎找不到。Sina Finance's repost of the Zidan Caijing report with WeBank's quantified figures (https://finance.sina.cn/2025-12-14/detail-inhauqsz3153445.d.html). Honest note: independent media repost, not a Tencent direct release; figures not independently reproduced. The contrast itself is information: TDSQL's users are "banks that signed contracts", not "engineers who blog" — frontline community production stories were nearly absent.
- 竞品差距
- OceanBase——蚂蚁/网商银行的同类故事,两者是"国产分布式银行核心"叙事的双子星;传统 IOE——成本差出数量级,是 TDSQL/OceanBase 共同的立论基础。"银行核心敢用"这张信任状两家各持一张,选型看的是存量生态(腾讯系 vs 蚂蚁系)。OceanBase — Ant/AntBank's sibling story; the two are the twin stars of the "domestic distributed bank core" narrative; traditional IOE — costs differ by orders of magnitude, the shared founding argument of TDSQL and OceanBase. Each holds one copy of the "banks trust it" credential; selection comes down to incumbent ecosystems (Tencent camp vs. Ant camp).
- 证据等级
- 具名生产(独立媒体转述);数字未独立复现;社区一线分享缺席(已标注)Named production (independent media repost); figures not independently reproduced; community frontline stories absent (stated)
