That No SQL Thing – Key / Value stores – Operations

time to read 2 min | 338 words

I mentioned before that the traditional API for Key / Value stores is pretty simplistic, Get/Put/Delete over blob values. That doesn’t really give us much options,

I have a long series of posts talking about how to do a whole host of operations using this minimal API.

It's good to see you're devoting a lot of attention to Key/Value data stores. I'm not exactly sure what your motivation for adopting the technology is but mine lies in its ability to create high-performance web sites / web services, something which I've articulated in my own recent post: NoSQL vs RDBMS http://www.servicestack.net/mythz_blog/?p=129.

Because of your reach, I think your single-handedly going to raise the adoption and awareness of the technology with your contribution of knowledge on the subject. Rhino DHT does look good, and knowing your high quality of work I would most likely have adopted if it wasn't for the existence of Redis. Unfortunately it's raw speed and advanced features like effortless replication, blocking pop's, publish/subscribe and bindings for almost every language in existence is going to be hard to match. In this way I consider Redis to be a broker facilitating high performance atomic communication across language boundaries.

I'm not sure if it's your intention, but merging 'Divan DB' and 'Rhino DHT' into a single integrated solution may be your biggest USP and will go a long way into solving one of Key/Value data stores biggest limitation - querying.
