Create a Lindorm data source

Security risk reminder

When you use OceanBase Data Transmission Service, you can automatically or manually add its public IP address CIDR blocks. However, this action may introduce security risks. Using this product, you acknowledge and accept these potential risks. You must also implement basic security protection measures. These measures include, but are not limited to, creating complex account passwords, restricting open ports for each CIDR block, using authentication for internal API communication, and regularly checking and restricting unnecessary IP address CIDR blocks.

OceanBase Data Transmission Service may adjust (add or delete) automatically added whitelists or security groups to meet business requirements and mitigate security risks. Do not use the IP address CIDR blocks in the whitelists or security groups for business needs unrelated to OceanBase Data Transmission Service. The OceanBase Data Transmission Service Service-Level Agreement (SLA) does not cover issues that arise from using these IP address CIDR blocks for other business purposes. For more information about whitelists and security groups, see Add a whitelist.

Procedure

1. Log on to the OceanBase Management Console.

2. In the navigation pane on the left, click Data Transmission > Data Source Management.

3. On the Data Source List page, click Create Data Source in the upper-right corner.

   

4. In the Create Data Source dialog box, set Data Source Type to Lindorm and configure the parameters.

   Parameter	Description
   Instance type	Only LindormTable (HBase mode only) is supported.
   Data source identity	The name can contain Chinese characters, numbers, and letters. The name cannot contain spaces and must be 32 characters or less.
   Cross-Alibaba Cloud account	Data Transmission Service lets you configure data migration or data synchronization tasks for instances under different Alibaba Cloud accounts. This enables cross-account data migration or data synchronization. Check this option as needed. If you check this option, enter the other party's Alibaba Cloud account. If you do not have the permissions of the Alibaba Cloud account, request authorization first. For more information about authorization, see Request cross-account authorization.
   Instance ID/Name	Select the Lindorm instance from the drop-down list. Only instances whose engine type includes wide tables are displayed. For more information about how to create an instance, see Create an instance.
   Username	The username for the Lindorm instance that is used for data migration or data synchronization. Create a separate privileged account for the data migration or data synchronization task. For more information, see Lindorm data source.
   Password	The password of the database user.
   Incremental synchronization option settings	The Kafka data source is used to store the incremental logs of the Lindorm database for consumption by Data Transmission Service. For more information about how to configure the delivery of data from Lindorm to Kafka, see Limits in "Overview of real-time change tracking". If you do not attach a Kafka data source, you cannot select Incremental Synchronization as the migration type when you create a data migration task from a Lindorm database to a MySQL tenant of an OceanBase database. Incremental data type: Only DEBEZIUM_V2 is supported. Kafka data source: You can select a Kafka data source that is saved in Data Transmission Service. For more information, see Create a Kafka data source. Important The Lindorm and Kafka data sources must be under the same vSwitch. Topic: You can select or enter a topic.
   Description (Optional)	The description of the data source.

5. Click Test Connection to verify the network connectivity between Data Transmission Service and the data source, and to validate the username and password.

6. After the connection test passes, click OK.
