redis-agent

I really find Redis convenient, but have run into some annoyances I'd like to abstract away. I'm not trying to replace existing libraries, such as carmine, but rather build on top of them.

Type is largely ignored when putting information in, and it creates complications when I try to pull it back out. If I have a number reflecting persistent state, every time I pull it out of redis I have to use read-string to turn it back into the type I put in. So a primary goal of this project is that any data that goes in looks the same as when it comes out.

When I think about redis, it's more as a giant map than a key/value store. I wish I could use the really nice facilities that exist to interact with maps and other data structures, rather than be stuck writing redis commands directly. Obviously there's a wrinkle in this plan, though, which is most interactions are going to result in side effects.

Side effects bring in the need for concurrency management, and we all know Clojure has these in spades. Refs and atoms are inappropriate for this type of issue, as they will both retry and write to Redis multiple times. That leaves us with agents, so this library will allow you to interact with redis as if it's a map agent.

Usage

Once I get this up on clojars, I'll update how to include the library here.

I don't want to write a quickstart that can get out of date with the actual code, so I've put it in a test file.
