This topic describes how to create a data source in OceanBase Cloud.
Background information
A data source is a collection of database connection information, including the connection address, port, username, and password. In OceanBase Cloud, by configuring a data source, you can quickly establish connections to databases for tasks such as data migration and job scheduling, improving operational efficiency and reliability.
Currently, OceanBase Cloud supports data sources from cloud providers including AWS, Huawei Cloud, Google Cloud, Alibaba Cloud, and Azure. It supports the following database types: OceanBase Database in MySQL-compatible mode and Oracle-compatible mode, MySQL databases (including Aurora MySQL, RDS MySQL, Cloud MySQL, PolarDB MySQL, Azure MySQL, and self-managed MySQL), Oracle databases (including RDS Oracle and self-managed Oracle), Kafka (including cloud instances and self-managed Kafka), PostgreSQL databases (including RDS PostgreSQL, Azure for PostgreSQL, and self-managed PostgreSQL), and self-managed TiDB databases.
Different database types require different methods for connecting to their corresponding data sources. Please select the appropriate connection method based on your database type.
OceanBase data sources (MySQL and Oracle compatibility modes)
For OceanBase Database, OceanBase Cloud provides three connection methods.
Quick connection to an OceanBase Cloud instance: This method applies to OceanBase Database instances created through the OceanBase Cloud console.
Endpoint connection or public network connection: This method applies to OceanBase Database deployed on infrastructure of AWS, Huawei Cloud, Google Cloud, Alibaba Cloud, or Azure.
Prerequisites
You have created an instance and a tenant in the OceanBase Cloud console (either MySQL or Oracle compatible mode is acceptable), and have a usable database and account.
You have the permissions of an Organization Administrator or Project Administrator in the OceanBase Cloud console.
Procedure
Log in to the OceanBase Cloud console.
In the left navigation bar, click Data Services > Data Source.
