TheHistoryParameters..::..MaintainHistoryStore Property

If false, history entries will be recorded internally and can only be retrieved via calls to GetThingHistory: this option is used primarily in conjunction with ClearHistory/RestartUpdateHistory for processing or transmitting streams of property changes with at least once delivery guarantees. If true, history entries will be recorded into a storage mirror that can be consumed directly by plug-ins. Calls to GetThingHistory will return null.
