I'm continuously impressed that new database technologies come forth, pushing productivity forward and pushing the bounds of what databases should be doing. I like to think a lot about Kdb, partly because I've used it extensively. Kdb, aside from it's database core functionality, can also be an app server. There's a natural concept of being able to open a listen socket or connect to other listenrs. Very quickly you can build distributed database systems with just a few lines of code. It's very powerful... I think the "way of thinking" in Kdb has yet to permeate into other database technologies.
