So if I do have a bucket that I regularly want a listing of the keys for (or really that I want to access all of the objects) what is the recommend procedure? Put the same 2i index on each object in the bucket and then do an index query on it? Is doing a mapred operation specifying a bucket as the input (instead of a list of key/value pairs) as bad as listing the keys in the bucket?

This is helpful if you want a known range of keys in a bucket. http://wiki.basho.com/Secondary-Indexes.html#Special-Fields Reid On Thu, Dec 1, 2011 at 11:37 AM, Andrew Thompson <[email protected]> wrote: > I think if you disable legacy keylisting, we'll just break a limb now. > > Seriously though, keylists are at least non-blocking in 1.0, so the > vnodes aren't prevented from doing any reads/writes while the keylist is > running.
