     [ https://issues.apache.org/jira/browse/HBASE-10342?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Liyin Tang updated HBASE-10342:
-------------------------------

    Description: 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 by id1. In such case, the rowkey bloom filter is able to cut more unnecessary seeks during the scan.
