ForgeKV – Redis-compatible KV server in Rust that scales with cores

I understand that the project is in his early stages, and documentation (README) is very much WIP. So, couple questions

    1. "SSD backed" - on-the-fly 100% time (like KVRocks), or requires same "save" like Redis does?
    2. (if it is like kvrocks) Do you have any perf numbers for DB sizes that are, say, 10x of RAM size?
