Does riak support optimistic concurrency? This KB article seems to indicate not: <a href="https://help.basho.com/entries/321522-can-riak-be-configured-to-fail-an-update-instead-of-generating-a-conflict" target="_blank">https://help.basho.com/entries/321522-can-riak-be-configured-to-fail-an-update-instead-of-generating-a-conflict</a>

<div>But if it doesn't, what is the meaning of the if_not_modified field in the PBC Store Object: <a href="http://wiki.basho.com/PBC-Store-Object.html" target="_blank">http://wiki.basho.com/PBC-Store-Object.html</a>?</div>

<div>If strict quorum is used (as described here: <a href="http://lists.basho.com/pipermail/riak-users_lists.basho.com/2012-January/007157.html" target="_blank">http://lists.basho.com/pipermail/riak-users_lists.basho.com/2012-January/007157.html</a>) will that
 allow optimistic concurrency to be implemented (once the bugs mentioned in the message are fixed)? Is there any update on those bugs?</div>
