Comments on: How YouTube scales MySQL for its large databases http://ebiquity.umbc.edu/blogger/2007/12/28/how-youtube-scales-mysql-for-its-large-databases/ EBB is the ebiquity research group\\\'s blog at the University of Maryland, Baltimore County (UMBC). We focus on technologies that facilitate the design, implementation and control of distributed, intelligent information systems -- mobile and pervasive computing, ad hoc networking, multiagent systems, knowledge representation and reasoning, and the semantic web. As the tides of technology ebb and flow, we hope the good ideas wash up on our beach and the bad ones drift back out to sea.

Horses for courses - quite simply - for this kind of task mysql beats postgres in terms of ease of scaling, query caching, etc - when you're dealing with very high traffic, then you're better off breaking up and simplifying your schema, etc in order to get the most speed, than using the "more powerful" RDBMS. @James,

There couldn't possible be a free, feature-rich, scalable dbms out there that you could use. Of course not.

If Flickr, etc, don't use them, why should we? Hi,
