I think I found the answer and it is no, I cannot control the sort. I
found the code here in riak_kv_wm_link_walker.erl:
links(Object) ->
MDs = riak_object:get_metadatas(Object),
lists:umerge(
[ case dict:find(?MD_LINKS, MD) of
{ok, L} ->
[ [B,K,T] || {{B,K},T} <- lists:sort(L) ];
error -> []
end
|| MD <- MDs ]).
Why run lists:sort? Shouldn't the sort be up to the user after he
gets the actual object? I don't understand why the sort processing is
necessary at the link phase. Thoughts?
