I'd never really thought about it as an alternative for Redis, but yeah if you can handle the huge performance decrease (which for many projects I imagine wouldn't matter in the slightest) that could maybe work pretty well!

Heh, well I am a solo developer with very low performance requirements so fewer moving pieces is the name of the game. Redis Just Works, but is yet another thing to manage. I know how to query SQL – I interface with Redis so infrequently I have to lookup the commands every time.

If/when the “library” feature gets incorporated, I could even imagine something crazy like using a library of SQLite databases to handle different backing services. ‘Redis’ cache server, job scheduler, log endpoint. Madness, but these are the idle thoughts before the caffeine has fully circulated.
