----------------------------------

             Summary: Allowing user to define levels of prefix of Rowkey to be also put into
BloomFilter
                 Key: HBASE-18394
                 URL: https://issues.apache.org/jira/browse/HBASE-18394
             Project: HBase
          Issue Type: Improvement
            Reporter: Ethan Wang


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
