Terms and Conditions

To connect to the OceanBase database you need

• OceanBase 3.1.0 or higher

• JDBC driver for OceanBase database, you can download the latest or specified version of ClickHouse JDBC driver from Maven repository. It is recommended to use OceanBase Connector/J 2.4.8 or above.

Connect to OceanBase

CREATE CATALOG oceanbase PROPERTIES (
    "type"="jdbc",
    "user"="root",
    "password"="password",
    "jdbc_url" = "jdbc:oceanbase://host:port/db",
    "driver_url" = "oceanbase-client-2.4.8.jar",
    "driver_class" = "com.oceanbase.jdbc.Driver"
)

remarks

jdbc_url defines the connection information and parameters to be passed to the OceanBase JDBC driver. Parameters for supported URLs can be found in OceanBase JDBC Driver Configuration.

Mode compatible

Doris will automatically recognize that OceanBase is in MySQL or Oracle mode when creating the OceanBase Catalog so that metadata can be parsed correctly.

Hierarchical mapping, type mapping, and query optimization in different modes are the same as the Catalog processing methods of MySQL or Oracle databases. Please refer to the documentation.
