Saw this earlier. Haven't tried it yet, but if the performance holds up this would be an interesting K/V store to try out.

Most people use Redis for this. Why another one?

This seems to be rather an embedded cache and not an external system.

Whether the (impressive looking) benchmarks are believable, is up to you.

Aha, thanks. Prevayler was like that too, iirc. I don't know if it is still around. Something comparable was done in Haskell that changed its name a few times and was slower than people hoped, so idk if that's still around either. I guess there are uses for these and it would be nice to have one in Rust.

Maybe not requiring the values to fit in memory, saving a lot of real estate there.
