> Where is this meme that RDBMSs do not scale coming from?

In my days it was more like "You can't afford RDBMSs at that scale". Reach a certain point and Larry gets a new yacht. Cheaper/open source offerings have moved that goal post by quite a bit.

Although it sometimes scares me how them poor databases get treated when performance is dropping. Little Jimmy JOIN is the first one to be put down, often way before there's a need for it.
