    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.

    Key features

    • Transparent Scalability

      An OceanBase cluster can be scaled to 1,500 nodes transparently, handling petabytes of data and a trillion rows of records.

    • Ultra-fast Performance

      The only distributed database that has refreshed both the TPC-C record, at 707 million tmpC, and the TPC-H record, at 15.26 million QphH @30000GB.

    • Real-time Operational Analytics

      A unified system for both transactional and real-time operational analytics workloads.

    • Continuous Availability

      OceanBase Database adopts the Paxos Consensus algorithm to achieve Zero RPO and less than 8 seconds of RTO. Supports intra-city/remote disaster recovery, enabling multi-activity in multiple locations and zero data loss.

    • MySQL Compatible

      OceanBase Database is highly compatible with MySQL, which ensures that zero or a few modifications are needed for migration.

    • Cost Efficiency

      The cutting-edge compression technology saves 70%–90% of storage costs without compromising performance. The multi-tenancy architecture achieves higher resource utilization.

    Quick start

    🔥 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"
    source ~/.oceanbase-all-in-one/bin/
    # quickly deploy OceanBase database
    obd demo

    🐳 Start with docker

    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
    2. Connect to the OceanBase Database instance:

      docker exec -it oceanbase-ce ob-mysql sys # Connect to the root user of the sys tenant.

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

    ️ Start with Kubernetes

    You can deploy and manage OceanBase Database instance in kubernetes cluster with ob-operator quickly. Refer to the document Quick Start for ob-operator to see details.
