question about riak siblings
Suppose I have two sources writing to the database, source A and source B. Next, suppose A and B both issue a write to the database so they spawn two siblings: [a1, b1]. Finally, suppose A writes another object using the metadata of the riak object returned when writing a2. This will lead to the following situation: [a1, b1, a2]. Upon the next read, the client will be presented with these three siblings. Is there a publicly exposed way to establish a strict ordering between a1 and a2?

Jeremy, What you are running into sounds a lot like the problems described in [1].

Re: question about riak siblings
Hi thanks, I was actually coming to the conclusion that to get this to work in my situation, I would need to embed a client side vector.
