Domestic Databases: TiDB, OceanBase, and Others – Insights from MySQL冲冲冲 Episode 8
In the eighth episode of the MySQL冲冲冲 live series, experts discuss the rise of Chinese domestic databases such as TiDB, OceanBase, and Jusheng, comparing their architectures, ecosystems, and market prospects while reflecting on the broader implications for MySQL‑based distributed systems.
The MySQL冲冲冲 program, co‑hosted by the IMG community and iKexing open‑source community, presents its eighth live episode focusing on Chinese domestic databases and asks which among TiDB, Jusheng, and OceanBase will ultimately prevail.
The host reviews the evolution of domestic databases, noting that earlier attempts like Dameng, Nanjing University’s General, and Renmin University’s JinCang were largely academic projects that failed to achieve large‑scale adoption, while newer systems are built on MySQL protocols.
TiDB is highlighted for its international orientation and modular architecture, though its market share remains modest. OceanBase is praised for its long development history, LSM‑Tree advantages, extensive financial‑sector deployment, and strong funding, but its closed‑source ecosystem slows adoption.
Jusheng’s CTO, formerly from DB2, built a custom storage engine resembling MongoDB; the engine is open‑source but limited in features, and Jusheng added MySQL protocol support in version 3.0, offering high SQL compatibility albeit with performance trade‑offs.
GaussDB, developed by Huawei, originated from PostgreSQL‑based telecom systems and now incorporates MySQL‑compatible components, though its cloud market presence is limited compared to TiDB and OceanBase.
The host concludes that OceanBase currently stands out as the most promising domestic database, especially due to its large‑scale financial use cases, while emphasizing that MySQL‑based distributed databases also qualify as domestic solutions and may dominate future financial core systems.
A Q&A segment follows, addressing questions about TDSQL, graph databases, and essential DBA skills, stressing the importance of programming proficiency (Java or Python), hands‑on project experience, and active participation in open‑source communities.
The episode wraps up with reflections on the season, thanking the iKexing community, and previewing the upcoming second season of MySQL冲冲冲.
