-- | Creates a value of 'ModifyClusterParameterGroup' with the minimum fields required to make a request.
--
-- Use one of the following lenses to modify other fields as desired:
--
-- * 'mcpgParameterGroupName' - The name of the parameter group to be modified.
--
-- * 'mcpgParameters' - An array of parameters to be modified. A maximum of 20 parameters can be modified in a single request. For each parameter to be modified, you must supply at least the parameter name and parameter value; other name-value pairs of the parameter are optional. For the workload management (WLM) configuration, you must supply all the name-value pairs in the wlm_json_configuration parameter.
