A distributed relational database with MySQL compatibility, built for clusters that must scale to petabytes without losing availability.
OceanBase is a distributed relational database developed entirely by Ant Group. It runs on clusters of ordinary servers rather than specific hardware architectures, which takes proprietary appliances out of the conversation when one database node stops being enough.
Availability and scaling both come from the Paxos protocol underneath its distributed structure. Data is replicated so a node failure costs no committed writes, and capacity grows by adding machines to the cluster.
The project states its characteristics in concrete numbers rather than adjectives.
- Transparent scalability: up to 1,500 nodes, petabytes of data and a trillion rows in one cluster.
- Benchmark results: 707 million tmpC on TPC-C and 15.26 million QphH at 30000GB on TPC-H.
- Storage efficiency: a claimed saving of 70 to 90 percent on storage costs.
- Real-time analytics: HTAP workloads served without standing up a separate analytical system.
- Recovery targets: zero data loss and a recovery time under 8 seconds.
- MySQL compatibility: migration from MySQL without rewriting the application layer.
Three routes get an instance running. An all-in-one installer deploys a stand-alone database on Linux, a Docker image starts a mini instance on a single port from Docker Hub, quay.io or ghcr.io, and ob-operator deploys and manages instances inside Kubernetes.
More than 2000 customers across financial services, telecom, retail and internet companies run it, and the source is Apache 2.0 with a public roadmap and developer documentation for compiling your own build.
