Hi Eric,
I don't get multiple siblings on a Riak GET for the key.
My buckets currently have allow_mult: false and last_write_wins: true
The n_val is the default 3
When I search, an example return is as follows, I can see the _yz_id has a
unique number on the end alright though?
Thanks for the help!
Jason
