I don't know about you, but when I first learned about Redis my initial thought was wow, why hasn't anyone done this before? My next thought was why put this functionality in a separate process? Why not just embed it in your own server code and skip the network path completely? Especially in a Service Oriented Architecture there's no need for an extra hop or extra software installation and configuration.
Now you can embed Redis-like code directly into your server with Vedis - an embeddable datastore C library built with over 70 commands similar in concept to Redis but without the networking layer since Vedis run in the same process of the host application. It's transactional, cross platform, thread safe, key-value, supports terabyte sized databases, has a GPL-like license (which isn't great for commercial apps), and supports an on-disk as well as in-memory datastore.
