Is there any method to get number of DataValues in History for a particular Node ?
the historyReadRaw returns the DataValue[], But we need only Count

historyReadProcessed() supports in theory aggregate functions, which also include Count. But our server SDK nor the applications do not support the historyReadProcessed() yet – and I am not aware of other servers either.
