What is OceanBase Database

# What is OceanBase Database OceanBase Database is a native distributed relational database. 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. ## 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. ## System architecture  ## Roadmap  Link: [4.0.0 function list](https://github.com/oceanbase/oceanbase/milestone/3) ## Case study For our success stories, see [Success stories](https://www.oceanbase.com/en/customer/home). ## Contributing Your contributions to our code will be highly appreciated.
