modify_db_parameter_group

Neptune.Client.modify_db_parameter_group(**kwargs)

Modifies the parameters of a DB 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 instance associated with the parameter group before the change can take effect.

Warning

After you modify a DB parameter group, you should wait at least 5 minutes before creating your first DB instance that uses that DB parameter group as the default parameter group. This allows Amazon Neptune to fully complete the modify action before the parameter group is used as the default for a new DB instance. This is especially important for parameters that are critical when creating the default database for a DB instance, 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 DescribeDBParameters command to verify that your DB parameter group has been created or modified.

Request Syntax

response = client.modify_db_parameter_group(
    DBParameterGroupName='string',
    Parameters=[
        {
            'ParameterName': 'string',
            'ParameterValue': 'string',
            'Description': 'string',
            'Source': 'string',
            'ApplyType': 'string',
            'DataType': 'string',
            'AllowedValues': 'string',
            'IsModifiable': True|False,
            'MinimumEngineVersion': 'string',
            'ApplyMethod': 'immediate'|'pending-reboot'
        },
    ]
)

Parameters:

• DBParameterGroupName (string) –

  [REQUIRED]

  The name of the DB parameter group.

  Constraints:

  • If supplied, must match the name of an existing DBParameterGroup.

• Parameters (list) –

  [REQUIRED]

  An array of parameter names, values, and the apply method for the parameter update. At least one parameter name, value, and apply method must be supplied; subsequent arguments are optional. A maximum of 20 parameters can be modified in a single request.

  Valid Values (for the application method): immediate | pending-reboot

  Note

  You can use the immediate value with dynamic parameters only. You can use the pending-reboot value for both dynamic and static parameters, and changes are applied when you reboot the DB instance without failover.

  • (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.

Return type:
