OceanBase is a distributed SQL database designed for high availability and strong consistency across multiple nodes and regions. It functions as a hybrid transactional and analytical processing engine, allowing real-time analytics and transactions to execute on a single data copy. The system also serves as a vector database engine for indexing and querying vector data to power semantic search and recommendation systems.
The platform features native compatibility layers for MySQL and Oracle, enabling the migration of legacy workloads without rewriting SQL code. It utilizes a Paxos-based distributed store for synchronous replication and implements a multi-tenant architecture that isolates CPU, memory, and I/O resources for different tenants within a single cluster.
The system covers a broad range of capabilities, including horizontal storage scaling, distributed transaction management, and hybrid row-columnar storage. It provides tools for cluster orchestration, automated load balancing via log-stream migration, and disaster resilience through multi-zone replication and automated failover.
Deployment and management are supported through a Kubernetes operator and a web monitoring dashboard.
