Regarding map/reduce emulation, I was thinking more along the lines of using a single bucket to achieve a similar effect. So then you can pull an object (column family aka row of columns), or via mr pull just x columns. Then to update, again use mr (instead of standard post,post,etc) to update individual columns of the "family" (by updating via mr, you reduce needless updating of *all* columns within the object)
So then a bucket would be a super-column in this scenario, using mr emulation within that same bucket. Again, I'm not saying this is a good idea or worthwhile whatsoever, but it seems it could be possible as long as standard save/retrieve methods are built in mr. <http://www.loomlearning.com/> *Jonathan Langevin Systems Administrator Loom Inc.
