Sharding isn't scaling. It's not application-transparent, and it's an operational nightmare.

  Sharding isn't scaling Sure sharding is scaling, although there are several types of sharding, with varying degrees of scalability. Usually people use a combination of both database (which what I was talking about) and table sharding (w/ replication,clustering,etc.) to achieve scalability. I've encountered several highly-scalable db environments like these. It's not application-transparent There are several databases that have features that can make sharding transparent to your application. and it's an operational nightmare it depends on the RDBMS that you're using.
