> For Time Series data, one common use case is get/scan by prefix of a row key. Such as:
> RowKey:    Scope.Metric.TimeStamp    
> Search by:  Scope*
> In these case bloom filter is not leveraged. However if we store every prefix of row key into bloomfilter that will be a big over head. Let user to store only the prefix of certain level will be a good thing to have
