fwiw, the company I work for has used keydb (multiple clusters) in production for years, under non-trivial load (e.g. millions of req per second). It did serve as a replacement to actual redis clusters, there were major improvements seen by the switch. I can't remember the actual gains as it was so long ago. I do remember it was an actual drop in replacement, as simple as replacing the redis binary and restarting the service. So if you can afford to, maybe try replacing a redis instance or two and see how it goes.
