Beating Oracle

The database, the software that stores and organises the data underneath every application, was for decades foreign territory, dominated by Oracle, IBM and Microsoft. China has spent the past few years reclaiming it, and the symbolic moment came on a benchmark leaderboard.

OceanBase, a distributed database built inside Alibaba’s Ant Group, first topped the industry-standard TPC-C benchmark in 2019, breaking a record Oracle had held for nine consecutive years, then pushed it to 707 million transactions per minute in 2020, a result documented in a peer-reviewed academic paper.^[1][2] A Chinese database was, on this measure, the fastest in the world.

The database was the last piece of foreign ground in the Chinese software stack. A benchmark record was the flag planted on it.

Substitution by policy

OceanBase is not alone; it anchors a deep domestic field, Alibaba’s PolarDB, PingCAP’s TiDB, Huawei’s GaussDB, Tencent’s TDSQL, plus Dameng, KingBase and GBase.^[3] Their rise is powered by policy as much as engineering. China’s “xinchuang” program, formalised in 2022, mandates the replacement of foreign software in government and state enterprises, turning a technical contest into a national procurement directive.^[4] From a market once up to 80% foreign, the shift toward domestic databases is now structural.^[3]

One honest caveat on the record. OceanBase’s TPC-C win used a large distributed cluster, so it is a legitimate benchmark result but not a like-for-like, single-machine comparison with Oracle; critics fairly note that total-throughput records reward scaling out. The achievement is real; the framing matters.

What this changes

The database revolution is one of China’s most complete import-substitution stories, combining genuine engineering achievement with a guaranteed policy-driven home market. That combination is unusually favourable: the domestic vendors have both a technical credential the world noticed and a captive government-and-SOE demand base that foreign rivals are being legislated out of. For investors the discipline is to distinguish the two engines — real capability, as in OceanBase’s cloud-native and financial-grade deployments, from mandated substitution that guarantees volume regardless of merit, and to favour the vendors that have both. The foundational layer of Chinese enterprise software is being rebuilt at home, and it is one of the stickiest, least reversible shifts in the whole technology stack.
