Create a PolarDB-O data source

Security risk notice

When you use OceanBase Data Transmission Service, you can add its public IP address CIDR blocks to a whitelist automatically or manually. This action may pose security risks. Using this product, you acknowledge and accept these potential risks. You must implement basic security protection measures. These measures include, but are not limited to, using complex account passwords, restricting open ports for each CIDR block, using authentication for internal API communication, and periodically reviewing and restricting IP address CIDR blocks that do not require access.

OceanBase Data Transmission Service automatically adjusts whitelists or security groups by adding or deleting entries based on factors such as business needs and security risks. Do not use the IP address segments in these whitelists or security groups for business purposes unrelated to OceanBase Data Transmission Service. Any issues that arise from using these IP address segments for other business purposes are not covered by the OceanBase Data Transmission Service SLA. For more information about the whitelists or security groups that Data Transmission Service automatically or manually adds, see the Add Whitelist module documentation.
