Bigtable is NOT any form of RDBMS. It's a highly optimised domain  
specific storage implementation designed specifically for scalability  
and redundancy. I suspect the people who wrote it are probably very  
careful about optimising every bit of their code too. Or perhaps they  
should just trust their optimiser. :-)
