modify_db_cluster_parameter_group#

DocDB.Client.modify_db_cluster_parameter_group(**kwargs)#

Modifies the parameters of a 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 or maintenance window before the change can take effect.

Warning

After you create a cluster parameter group, you should wait at least 5 minutes before creating your first cluster that uses that cluster parameter group as the default parameter group. This allows Amazon DocumentDB to fully complete the create action before the parameter group is used as the default for a new cluster. This step is especially important for parameters that are critical when creating the default database for a cluster, such as the character set for the default database defined by the character_set_database parameter.

Parameters:

  • DBClusterParameterGroupName (string) –

    [REQUIRED]

    The name of the cluster parameter group to modify.

  • Parameters (list) –

    [REQUIRED]

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

    • (dict) –

      Detailed information about an individual 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.

Return type:
