Currently a very early version of course, but it’s there in trunk if you want to play with it. Just have libcurl and libevent installed and you can submit queries via HTTP and JSON. Of course, the next steps are getting a true non-sql interface going and seeing how people go with it.
So there’s a bit of a swelling around the idea of NoSQL. That is, databases that don’t have an SQL interface in front of them – with the promise of better performance. With a well designed backend, this is no doubt the case.
A flexible query language is rather useful though. I think we’ll see the rise of AlsoSQL. That is systems that present a fast and simple protocol along with a SQL interface.
This hybrid system has seen use for many years. MySQL Cluster is one such example. SQL through MySQL Server, NoSQL through NDB API.
With Drizzle, I feel we’ll be in a pretty good position to offer non-sql based protocols and access methods to existing storage engines.
