# What is OceanBase database
|
|
|
|
OceanBase Database is a native distributed relational database. It is developed entirely by Alibaba and Ant Group. OceanBase Database is built on a common server cluster. Based on the Paxos protocol and its distributed structure, OceanBase Database provides high availability and linear scalability. OceanBase Database is not dependent on specific hardware architectures.
|
|
|
|
OceanBase Database has these features:
|
|
|
|
- High availability
|
|
Single server failure recovers automatically. OceanBase Database supports cross-city disaster tolerance for multiple IDCs and zero data loss. OceanBase Database meets the financial industry Level 6 disaster recovery standard (RPO=0, RTO<=30 seconds).
|
|
- Linear scalability
|
|
OceanBase Database scales transparently to applications and balances the system load automatically. Its cluster can contain more than 1500 nodes. The data volume can reach petabytes. The records in a single table can be more than a trillion rows.
|
|
- Highly compatible with MySQL
|
|
OceanBase Database is compatible with MySQL protocol and syntax. You can access to OceanBase Database by using MySQL client.
|
|
- High performance
|
|
OceanBase Database supports quasi memory level data change and exclusive encoding compression. Together with the linear scalability, OceanBase Database provides high performance.
|
|
- Low cost
|
|
OceanBase Database uses PC servers and cheap SSDs. Its high storage compression ratio and high performance also reduce the storage cost and the computing cost.
|
|
- Multi-tenancy
|
|
OceanBase Database supports native multi-tenancy architecture. One cluster supports multiple businesses. Data is isolated among tenants. This reduces the deployment, operation, and maintenance costs.
|
|
|
|
OceanBase Database supports the entire core business of Alipay and the core systems of hundreds of financial institutions, such as banks and insurance companies.
