Any time these "much faster than Redis" databases come up, the sysadmin in me wonders how many people have had actual performance limitation issues with Redis. I've seen Redis servers handle hundreds of GB of traffic per hour. I've worked at companies where Aerospike and others are proposed as replacements for Redis because "they're faster" - and I point out the 98% idle CPUs on the Redis server, and the near-100%-usage CPUs on the app server fleet and mouth "But... why?"
Replacing Redis with "something faster" is a bit like removing the doors on a car because "lighter means faster!". It might look good on a racetrack, but it's about as pragmatic as climbing through a window every morning before setting off for work.
