# 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
