Written in Go? I wonder what the GC pressure is going to look like with many small keys. I've written a redis clone in Go a few years ago and the GC pauses when reaching a few GBs of utilization were awful. Granted the Go GC has improved considerably since but it's still going to be noticeable I bet.

Probably managable with a good slab allocator.

Yeah, I've seen people do that but I've glanced the code, it's certainly not the case here.

We're aware of the issues this could cause and we will be looking into relieving GC pressure

Great. Good luck. As someone who's worked on the redis codebase, I suggest you take a good look at some of the design decisions and optimizations that project took, e.g. wrt persistence and replication.
