Is there a more technical explanation post somewhere? I'm definitely curious how it works, and I like the core idea quite a bit - I'm fairly convinced that WASM uses like this are going to grow immensely, and "it's just a global mutex/single thread" reduces complexity so much that it's always interesting to see where it's possible to use.
The latency+throughout brings many questions though, like "are you holding responding to writes and any reads that occur after until changes are written to disk" and "if so I kinda assume that change log is constantly streamed to disk with a moving high water mark for responses". I can generally see how that'd hit such benchmarks, especially with non-dirty reads being near instant, but details are always interesting.
