Riak Off Siblings

[Konstantin74R]

Hi,
I use riak 2.1.1 with riak CS 2.1.0
My application don't need a siblings, only last values. but in documentation -
"Setting both allow_mult and last_write_wins to true necessarily leads to unpredictable behavior and should always be avoided."

What happens if I use allow_mult and last_write_wins in true?

How can i resolve my situation ?
