Data Nodes

Constraints on data nodes are as follows:

  • Data nodes can be only RDS for MySQL and GaussDB(for MySQL) instances of versions 5.7 and 8.0.
  • DDM cannot connect to MySQL instances using SSL connections.
  • Case sensitivity support cannot be enabled for MySQL instances.
    • If you are using MySQL 5.7, select Case insensitive for Table Name when you create a MySQL instance, or set lower_case_table_names to 1 on the Parameters page after you complete the creation.
    • If you are using MySQL 8.0, select Case insensitive for Table Name when you create a MySQL instance.
  • Modifying configurations of a data node may result in an exception in using your DDM instance. After the modification, click Synchronize Data Node Information on the Data Nodes page to synchronize changes from the data node to DDM.
  • DDM data nodes do not support GBK character sets.
