modify_db_cluster_parameter_group

modify_db_cluster_parameter_group(**kwargs)

Modifies the parameters of a DB cluster parameter group. To modify more than one parameter, submit a list of the following: ParameterName , ParameterValue , and ApplyMethod . A maximum of 20 parameters can be modified in a single request.

Note

Changes to dynamic parameters are applied immediately. Changes to static parameters require a reboot without failover to the DB cluster associated with the parameter group before the change can take effect.

Warning

After you create a DB cluster parameter group, you should wait at least 5 minutes before creating your first DB cluster that uses that DB cluster parameter group as the default parameter group. This allows Amazon Neptune to fully complete the create action before the parameter group is used as the default for a new DB cluster. This is especially important for parameters that are critical when creating the default database for a DB cluster, such as the character set for the default database defined by the character_set_database parameter. You can use the Parameter Groups option of the Amazon Neptune console or the DescribeDBClusterParameters command to verify that your DB cluster parameter group has been created or modified.

Parameters

• DBClusterParameterGroupName (string) --

  [REQUIRED]

  The name of the DB cluster parameter group to modify.

• Parameters (list) --

  [REQUIRED]

  A list of parameters in the DB cluster parameter group to modify.

  • (dict) --

    Specifies a parameter.

    • ParameterName (string) --

      Specifies the name of the parameter.

    • ParameterValue (string) --

      Specifies the value of the parameter.

    • Description (string) --

      Provides a description of the parameter.

    • Source (string) --

      Indicates the source of the parameter value.

    • ApplyType (string) --

      Specifies the engine specific parameters type.

    • DataType (string) --

      Specifies the valid data type for the parameter.

    • AllowedValues (string) --

      Specifies the valid range of values for the parameter.

    • IsModifiable (boolean) --

      Indicates whether ( true ) or not ( false ) the parameter can be modified. Some parameters have security or operational implications that prevent them from being changed.

    • MinimumEngineVersion (string) --

      The earliest engine version to which the parameter can apply.

    • ApplyMethod (string) --

      Indicates when to apply parameter updates.
