[jira] [Created] (HBASE-10342) RowKey Prefix Bloom Filter

Liyin Tang created HBASE-10342:
----------------------------------

             Summary: RowKey Prefix Bloom Filter
                 Key: HBASE-10342
                 URL: https://issues.apache.org/jira/browse/HBASE-10342
             Project: HBase
          Issue Type: New Feature
            Reporter: Liyin Tang


When designing HBase schema for some use cases, it is quite common to combine multiple information within the RowKey. For instance, assuming that rowkey is constructed as md5(id1) + id1 + id2, and user wants to scan all the rowkeys which starting at id1 . In such case, the rowkey bloom filter is able to cut more unnecessary seeks during the scan.
