I believe you're not allowed to have ordered tables that are only on

I've been vexed by this too, trying to design a replacement for our
current system (based on MySql). I'm thinking either an ordered RAM-only
copy of just the keys as a secondary table, or building a second table
with a column for each attribute I want to sort on, maintaining a
skiplist in each column. (My ordering criteria don't change once the
record is written, but it gets messier if you want to be updating the
key it's ordered on.)
(Sorry if you get that twice.)
