<caveat> There's some more detailed explanation of this floating  
around the site, and I haven't looked in detail at this in a long time  
</caveat> but IIRC this was highly optimized for append-only event  
streams and uses a kind of column-oriented storage paradigm.  It's  
much more like big array processing than it is like free-form  
relational databases.  I don't know for sure but I doubt seriously  
that there's any sort of ACID type guarantee, or even multi-user  
concurrency control of any sort.
