WebMynd has a great little post about extending SQLAlchemy to back Amazon’s Simple Storage Service. I wasn’t even aware of MapperExtension until now. If you love reading about all the little nooks and crannies of SQLAlchemy, check this out. I also just realized that the Mike Bayer who commented on bor.borygmus’s first grumble is the same person who created SQLAlchemy, which is marvelous.
