Hi spats,

thank you for your message. 


Let me clarify a mistake I mentioned in my original post: I have 11 regions
for that billions of rows table from 3 regions servers actually. 

I'm gonna answer your questions bellow:

1> 
This is the pattern of my rowkeys: "<hash>#<field_1>#<field_2>#0x<field_3>",
where <hash> is the sha2 of <field_1>

I wanna to retrieve rows whose start keys  as
"<hash>#<field_1>#<field_2>#0x00000" and stoprows as
"<hash>#<field_1>#<field_2>#0xfffff0", where the fields <hash>, <field_1>,
<field_2> in both start and stop rows are the same. Just <field_3> is
different.

What do you think about this pattern? I hashed the most significant part of
the rowkey and just changed the less significant part when searching the
ranges I want. 

Thank you
