**OceanBase Database** is a distributed relational database. It is developed entirely by Ant Group. 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, OceanBase Database provides high availability and linear scalability. OceanBase Database is not dependent on specific hardware architectures.
# Key features
- **Transparent Scalability**
An OceanBase cluster can be scaled out 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 TPC-C record, at 707 million tmpC, and 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 Paxos Consensus algorithm to achieve Zero RPO and less than 8 seconds of RTO.
- **MySQL Compatible**
OceanBase Database is highly compatible with MySQL, which ensures that zero or few modification is needed for migration.
- **Cost Effeciency**
The cutting-edge compression technology saves 70%-90% of storage costs without compromising performance. The multi-tenancy architecture achieves higher resource utilization.
