> 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.
