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.

Start an OceanBase Database instance: ```shell # Deploy a mini standalone instance. docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d oceanbase/oceanbase-ce ``` 2. Connect to the OceanBase Database instance: ```shell docker exec -it oceanbase-ce ob-mysql sys # Connect to the root user of the sys tenant. ``` See also [Quick experience](https://en.oceanbase.com/docs/community-observer-en-10000000000829647) or [Quick Start (Simplified Chinese)](https://open.oceanbase.com/quickStart) for more details. ## ☸️ Start with Kubernetes You can deploy and manage OceanBase Database instance in kubernetes cluster with [ob-operator](https://github.com/oceanbase/ob-operator) quickly.
