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.
OceanBase Cloud supports data sources deployed on Alibaba Cloud, AWS, Huawei Cloud, Azure, and Google Cloud. Supported database types include OceanBase Database, MySQL, Oracle, Kafka, PostgreSQL, TiDB, HBase, Lindorm, RocketMQ, DataHub, AnalyticDB for MySQL (ADB), and PolarDB-X 2.0. Supported cloud providers and instance types vary by database type. See the following sections for details.
The connection method for a data source varies depending on the database type. 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 four connection methods.
Quick connection to an OceanBase Cloud instance: This method is suitable for OceanBase Database instances created through the OceanBase Cloud console.
Endpoint connection, public network connection, or peering connection: Endpoint and public network connections apply to OceanBase Database deployed on Alibaba Cloud, AWS, Huawei Cloud, Azure, or Google Cloud. Peering connections apply to self-managed OceanBase Database deployed on Alibaba Cloud, AWS, or Google Cloud.
Prerequisites

This authentication method allows for dynamic user changes, and user data is stored in Zookeeper. Before starting a broker, communication with Zookeeper is required to create a communication user between Zookeeper and the broker. However, this authentication method requires configuring the username and password in plaintext. - Kafka supports SCRAM-SHA-512, which can be used with TLS to perform secure authentication.
