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.
