What Are the Precautions for Creating Data Connections?

  • RDS data connections depend on OBS. If OBS is unavailable in the same region as DataArts Studio, RDS data connections are not supported.
  • For host connections, only Linux hosts are supported.
  • If changes occur in the connected data lake (for example, the MRS cluster capacity is expanded), you need to edit and save the connection.
  • If the data lake authentication information in a data connection changes (for example, the password expires), the data connection becomes invalid. Ensure that the data lake authentication information is permanently valid to prevent any loss caused by connection failures.
  • DataArts Studio does not support MRS clusters whose Kerberos encryption type is aes256-sha2,aes128-sha2, and only supports MRS clusters whose Kerberos encryption type is aes256-sha1,aes128-sha1.

  • The data lake to connect communicates with the DataArts Studio instance properly.
    • If the data lake is an on-premises database, a public network or a dedicated connection is required. Ensure that the host where the data source is located can access the public network and the port has been enabled in the firewall rule.
    • If the data lake is a cloud service (such as DWS and MRS), the following requirements must be met for network interconnection:
      • If the CDM cluster in the DataArts Studio instance and the cloud service are in different regions, a public network or a dedicated connection is required.
      • If the CDM cluster in the DataArts Studio instance and the cloud service are in the same region, VPC, subnet, and security group, they can communicate with each other by default. If they are in the same VPC but in different subnets or security groups, you must configure routing rules and security group rules. For details about how to configure routing rules, see Configuring Routing Rules. For details about how to configure security group rules, see Configuring Security Group Rules.
      • The cloud service instance and the DataArts Studio workspace belong to the same enterprise project. If they do not, you can modify the enterprise project of the workspace.
