Are triplestores good databases?

A useful post from Adam Bosworth: Where have all the good databases gone. He’s talking in the context of Amazon-size enterprise DBs, which generally means RDBMSs. He lists the three things users of (large) databases tend to ask for:

1. Dynamic schema
2. Dynamic partitioning of data across large dynamic numbers of machines
3. Modern indexing

“Users of databases don’t believe that they are getting any of these three.”
