nalgeon/redka v0.1.0

on GitHub

Redka aims to reimplement the good parts of Redis with SQLite, while remaining compatible with the Redis API. The first release on the way to 1.0 brings string commands, key management and transactions.

All commands are available via the Redis wire protocol (RESP) and the Go API.
