And sounds very much like what we discussed about back in 2007 at Austin, when we first thought about using CouchDB as a backend, or with Stefan experimentation wih HBase.
Now, even if it sounds interesting, there are many many issues with this approach. One of them is to guarantee the atomicity of modifications, something thatis not especially enforced by Hadoop, AFAICT. Not to mention the fact that updating indices on the fly is just extremely hazardous when you have no transactions... All in all, with HBase, we have something similar, but it's far from being finished. At leats, it works, bit it needs to be tested in a larger scale. -- Regards, Cordialement, Emmanuel Lécharny www.iktek.com
