English | [中文版](README_CN.md) **OceanBase Database** is a distributed relational database. It is developed entirely by Ant Group. The OceanBase Database is built on a common server cluster. Based on the [Paxos](https://lamport.azurewebsites.net/pubs/lamport-paxos.pdf) protocol and its distributed structure, the OceanBase Database provides high availability and linear scalability. The OceanBase Database is not dependent on specific hardware architectures. # Key features - **Transparent Scalability** An OceanBase cluster can be scaled to 1,500 nodes transparently, handling petabytes of data and a trillion rows of records. - **Ultra-fast Performance** The only distributed database that has refreshed both the TPC-C record, at 707 million tmpC, and the TPC-H record, at 15.26 million QphH @30000GB. - **Real-time Operational Analytics** A unified system for both transactional and real-time operational analytics workloads. - **Continuous Availability** OceanBase Database adopts the Paxos Consensus algorithm to achieve Zero RPO and less than 8 seconds of RTO. Supports intra-city/remote disaster recovery, enabling multi-activity in multiple locations and zero data loss. - **MySQL Compatible** OceanBase Database is highly compatible with MySQL, which ensures that zero or a few modifications are needed for migration. - **Cost Efficiency** The cutting-edge compression technology saves 70%–90% of storage costs without compromising performance. The multi-tenancy architecture achieves higher resource utilization.
