Redka aims to reimplement the good parts of Redis with SQLite, while remaining compatible with Redis API.

A neat project! It's a wrapper around sqlite that supports the redis protocol.

Here's the implementation of the set command, for example. It ends up pretty abstracted from the database.

Performance is, unsurprisingly, much worse than redis. Reads are approximately 2x slower on a simple benchmark run, writes between 4.5x - 6x slower. It also has very different characteristics, being an ACID-compliant wrapper rather that wants to be safe on disk rather than a highly performant in-memory store that will write to disk in any of several potentially unsafe ways.

I'm not quite sure if I would ever want to use it! But it's neat.
