OceanBase

OceanBase is a distributed relational database that provides high availability, scalability, and compatibility with MySQL.

About

OceanBase is a distributed relational database management system (RDBMS) that provides high availability, scalability, and strong consistency. It’s designed to handle large-scale data processing and is compatible with MySQL, making it easy for developers to migrate from MySQL to OceanBase.

Requirements

Database User

This source only uses standard authentication. You will need to create an OceanBase user to login to the database with. OceanBase supports MySQL-compatible user management syntax.

Network Connectivity

Ensure that your application can connect to the OceanBase cluster. OceanBase typically runs on ports 2881 (for MySQL protocol) or 3881 (for MySQL protocol with SSL).

Example

sources:
    my-oceanbase-source:
        kind: oceanbase
        host: 127.0.0.1
        port: 2881
        database: my_db
        user: ${USER_NAME}
        password: ${PASSWORD}
        queryTimeout: 30s # Optional: query timeout duration

Tip

Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file.

Reference

field	type	required	description
kind	string	true	Must be “oceanbase”.
host	string	true	IP address to connect to (e.g. “127.0.0.1”).
port	string	true	Port to connect to (e.g. “2881”).
database	string	true	Name of the OceanBase database to connect to (e.g. “my_db”).
user	string	true	Name of the OceanBase user to connect as (e.g. “my-oceanbase-user”).
password	string	true	Password of the OceanBase user (e.g. “my-password”).
queryTimeout	string	false	Maximum time to wait for query execution (e.g. “30s”, “2m”). By default, no timeout is applied.

Features

MySQL Compatibility

OceanBase is highly compatible with MySQL, supporting most MySQL SQL syntax, data types, and functions. This makes it easy to migrate existing MySQL applications to OceanBase.

High Availability

OceanBase provides automatic failover and data replication across multiple nodes, ensuring high availability and data durability.

Scalability

OceanBase can scale horizontally by adding more nodes to the cluster, making it suitable for large-scale applications.

Strong Consistency

OceanBase provides strong consistency guarantees, ensuring that all transactions are ACID compliant.
