A JSON string that consists of parameters and their values in the parameter template. Format: {"Parameter 1":"Value of Parameter 1","Parameter 2":"Value of Parameter 2"...}. For more information about the parameters that can be modified, see Modify the parameters of an ApsaraDB RDS for MySQL instance or Modify the parameters of an ApsaraDB RDS for PostgreSQL instance.

Note
  • If ModifyMode is set to Individual and this parameter is specified, the new parameters overwrite the parameters in the original parameter template.

  • If you set ModifyMode to Collectivity and specify this parameter, the new parameters are added to the original parameter template, or the parameters in the original parameter template are modified.

  • If you do not specify this parameter, the parameters in the original parameter template remain unchanged.

{"back_log":"3000"}

ModifyModestringNo

The modification mode of the parameter template. Valid values:

  • Collectivity (default): adds new parameters or modifies parameters in the original parameter template.
