Liyin Tang commented on HBASE-10342:
------------------------------------

Interesting.... If the most significant part of the row key is evenly 
distributed across the row key space, usually we don't need to salt the table, 
right ?

> 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.
