    Last Updated:Jun 03, 2024

    Before you create a data migration or synchronization project, you must create the data sources. This topic describes how to create a PolarDB data source by using the data transmission service.

    Background

    PolarDB-X 1.0 is a PolarDB distributed database developed in house by Alibaba Group. It is integrated with a distributed SQL engine and an exclusively developed distributed storage X-DB and is designed based on the cloud-native integrated architecture. PolarDB-X 1.0 supports over ten million concurrent requests and provides a large storage capacity for hundreds of petabytes of data. For more information, see Product overview.

    Prerequisites

      Instance Type

      The type of the instance. At present, only Alibaba Cloud PolarDB-X 1.0 instance is supported.

      Important

      The data transmission service does not support mounting a private RDS database to a PolarDB-X 1.0 instance.

      Data Source Identifier

      The data source identifier, which must contain less than 32 characters in length and cannot contain spaces. Supported characters are letters, digits, hyphens (-), commas (,), and underscores (_).

      Select the ID of the target PolarDB-X 1.0 instance from the drop-down list.

      Username

      The name of the PolarDB-X 1.0 database user that is used for data migration or synchronization.

      We recommend that you create an independent database user for data migration or synchronization and create the same user and password in the underlying RDS database. For more information, see Manage accounts.

      Password

      The password of the database user.

      Important

      You must create the same user and password in the underlying RDS database.

      Remarks (Optional)

      Additional information about the data source.

    5. Click Test Connection to verify the network connection between the data transmission service and the data source, as well as the validity of the username and password.

    6. After the test is passed, click OK.
