Oceanbase

Distributed relational database built for high availability, horizontal scalability, and financial-grade consistency. Delivers both transactional and analytical workloads on a single engine with MySQL and Oracle compatibility modes, reducing the need for separate OLTP and OLAP clusters.

OceanBase powers Alipay's Double 11 shopping festival and serves financial institutions such as Industrial and Commercial Bank of China, China Construction Bank, and Bank of Nanjing, plus internet companies including Trip.com, Meituan, Kuaishou, and Bilibili. Stands out from traditional MySQL or PostgreSQL by offering HTAP in one system, Paxos-based consensus for zero RPO and sub-8-second RTO, and transparent scaling to thousands of nodes.

Key capabilities:

• MySQL and Oracle compatibility modes for easier migration from existing systems
• Transparent scalability to 1,500 nodes with petabytes of data
• Single-engine HTAP for real-time analytics on live transactional data
• Paxos-based replication for city-level disaster tolerance
• High compression reducing storage footprint by 70–90%

Teams running high-throughput transactional systems with real-time analytics needs can consolidate workloads onto one database. Financial services and e-commerce platforms benefit from strong consistency and proven resilience. MySQL and Oracle users can migrate with minimal application changes, using standard drivers and existing tooling.
