I recently wrote about Kyoto Tycoon (KT), a fast key/value database server. KT databases may be ordered (B-Tree / red-black tree) or unordered (hash table), and persistent or stored completely in-memory. Among other things, I'm using KT's hash database as a cache for things like HTML fragments, RSS feed data, etc. KT supports automatic, time-based expiration, so using it as a cache is a natural fit.
Besides using KT as a cache, in the past I have also used Redis and Sqlite. So I've released a small library I'm calling ucache which can be used with these storage backends and has a couple nice features. I will likely flesh it out and add support for additional storages as I find time to work on it.
I saw an excellent article recently describing how to implement the fire effect seen in the trailer for the N64/PlayStation ports of the DooM game. I figured this would be neat to put on the page displayed whenever there's a server error. I already have an awesome 404 page, and now I'm equally happy with the 500 page.
- On-disk hash table for fast random access
- On-disk b-tree for ordered collections
- Server supports thousands of concurrent connections
- Embedded lua scripting
- Asynchronous replication, hot backups, update logging
- Exceptional performance
