OceanBase Database is a distributed relational database. It is developed entirely by Ant Group. The OceanBase Database is built on a common server cluster. Based on the Paxos protocol and its distributed structure, the OceanBase Database provides high availability and linear scalability. The OceanBase Database is not dependent on specific hardware architectures. It also supports vector database functionality, enabling efficient vector search for AI and large-scale retrieval scenarios.

Key features

• Vector Search: Supports vector indexing and efficient queries, making it ideal for AI applications, recommendation systems, and semantic search, providing high throughput and low-latency vector search capabilities.
• Transparent Scalability: 1,500 nodes, PB data and a trillion rows of records in one cluster.
• Ultra-fast Performance: TPC-C 707 million tmpC and TPC-H 15.26 million QphH @30000GB.
• Cost Efficiency: saves 70%–90% of storage costs.
• Real-time Analytics: supports HTAP without additional cost.
• Continuous Availability: RPO = 0(zero data loss) and RTO < 8s(recovery time)
• MySQL Compatible: easily migrated from MySQL database.

Quick start

See also Quick experience or Quick Start (Simplified Chinese) for more details.

🔥 Start with all-in-one

You can quickly deploy a stand-alone OceanBase Database to experience with the following commands:

Note: Linux Only

# download and install all-in-one package (internet connection is required)
bash -c "$(curl -s https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/download-center/opensource/oceanbase-all-in-one/installer.sh)"
source ~/.oceanbase-all-in-one/bin/env.sh

# quickly deploy OceanBase database
obd demo

🐳 Start with docker

Note: We provide images on dockerhub, quay.io and ghcr.io. If you have problems pulling images from dockerhub, please try the other two registries.

1. Start an OceanBase Database instance:

   # Deploy a mini standalone instance.
   docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d oceanbase/oceanbase-ce
   
   # Deploy a mini standalone instance using image from quay.io.
   # docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d quay.io/oceanbase/oceanbase-ce
   
   # Deploy a mini standalone instance using image from ghcr.io.
   # docker run -p 2881:2881 --name oceanbase-ce -e MODE=mini -d ghcr.io/oceanbase/oceanbase-ce
   

2. Connect to the OceanBase Database instance:

   docker exec -it oceanbase-ce obclient -h127.0.0.1 -P2881 -uroot # Connect to the root user of the sys tenant.
