Sequin unkindly speculated that the major database vendors have ignored Database Sharding for commercial reasons.
There are a lot of expensive ways to scale your database – all of which are highly touted by the big three database vendors because, well, they want to sell you all types of really expensive stuff. Despite what an “engagement consultant” might tell you though, most of the high-traffic websites on the web (google, digg, facebook) rely on far cheaper and better strategies: the core of which is called sharding.
What’s really astounding is that sharding is database agnostic – yet only the MySQL crowd seem to really be leveraging it. The sales staff at Microsoft, IBM and Oracle are doing a good job selling us expensive solutions.
