DiskCache

DiskCache

Grant Jenks built DiskCache as an alternative caching backend for Django (also usable without Django), using a SQLite database on disk. The performance numbers are impressive - it even beats memcached in microbenchmarks, due to avoiding the need to access the network.

The source code (particularly in core.py) is a great case-study in SQLite performance optimization, after five years of iteration on making it all run as fast as possible.
