Key Range

Hi,
Using 0.7.4, BOP, and RF=3, Write->QUORUM and Read->ONE "NO UPDATES"
How does get_range_slices using Key Range works? Is it possible to get 
out of date list of keys?
If a key is inserted into 2 Nodes and after that a read with a key range 
is issued, is it possible to have the 3 Node (that does not have this 
key yet) return the range with out that key?

Regards,

W=Q R=1 is not guaranteed to be consistent, no.  you need R=W=Q for that.
