**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.

## How to deploy
### 🔥 Deploy by all-in-one
You can quickly deploy a standalone OceanBase Database to experience with the following commands.
**Note**: Linux Only
```shell
# download and install all-in-one package (internet connection is required)
bash -c "$(curl -s https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/download-center/opensource/oceanbase-all-in-one/installer.sh)"
source ~/.oceanbase-all-in-one/bin/env.sh
# quickly deploy OceanBase database
obd demo
```
### 🐳 Deploy by docker
1. Pull OceanBase image (optional)
```shell
docker pull oceanbase/oceanbase-ce
```
2. Start an OceanBase Database instance
```shell
# Deploy an instance with the maximum specifications supported by the container.
docker run -p 2881:2881 --name obstandalone -e MINI_MODE=0 -d oceanbase/oceanbase-ce
# Or deploy a mini standalone instance.
docker run -p 2881:2881 --name obstandalone -e MINI_MODE=1 -d oceanbase/oceanbase-ce
```
3. Connect to the OceanBase Database instance
```shell
docker exec -it obstandalone ob-mysql sys # Connect to the root user of the sys tenant.
docker exec -it obstandalone ob-mysql root # Connect to the root user of the test tenant.
docker exec -it obstandalone ob-mysql test # Connect to the test user of the test tenant.
