It is developed entirely by 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 and 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. +## Core features + +- Scalable OLTP + - Linear scalability by adding nodes to the cluster + - Partition-level leader distribution and transparent data shuffling + - Optimized performance for distributed transaction through "table group" technology + - High concurrency updates on hot row through early lock release (ELR) + - 80000+ connections per node and unlimited connections in one instance through multi threads and coroutines + - Prevent silent data corruption (SDC) through multidimensional data consistency checksum + - No.1 in TPC-C benchmark with 707 million tpmC +- Operational OLAP + - Process analytical tasks in one engine, no need to migrate data to OLAP engine + - Analyze large amounts of data on multiple nodes in one OceanBase cluster with MPP architecture + - Advanced SQL engine with CBO optimizer, distributed execution scheduler and global index + - Fast data loading through parallel DML, and with only 50% storage cost under compression + - Broke world record with 15.26 million QphH in TPC-H 30TB benchmark in 2021 +- Multi-tenant + - Create multiple tenants (instances) in one OceanBase cluster with isolated resource and access + - Multidimensional and transparently scale up/out for each tenant, and scaling up takes effect immediately + - Database consolidation: multi-tenant and flexible scaling can achieve resource pooling and improve utilization + - Improve management efficiency and reduce costs without compromising performance and availability ## Quick start +See [Quick start](https://open.oceanbase.com/quickStart) to try out OceanBase Database. -Refer to the [Get Started guide](https://open.oceanbase.com/quickStart) to try out OceanBase Database with OBD. -Refer to the [Try with Docker](https://hub.docker.com/repository/docker/oceanbase/oceanbase-ce) to try OceanBase Database with docker. - -## Documentation - -- English (Coming soon) -- [Simplified Chinese](https://open.oceanbase.com/docs) (简体中文) - -## Supported clients - -- [OBClient](https://github.com/oceanbase/obclient) -- [MySQLClient](https://dev.mysql.com/downloads/) - -## Licencing - -OceanBase Database is under [MulanPubL - 2.0](http://license.coscl.org.cn/MulanPubL-2.0) license.
