Should I write my own Redis?

Hello,

there is an excellent library for golang which allows you to implement the redis server protocol: https://github.com/tidwall/redcon

I would like to put in the effort to implement most redis commands there and map them to SQL, so that all data can be saved inside a fine tuned sqlite.

Essentially if this is implemented we would have a database compatible to redis, the difference is that data is saved to disk and not to RAM.

Is there a use case for that? Do people want that? There is some interesting things that could be done with that but I am not sure if the world needs this.
