@xuu I was hoping to read about more technical details of SSTables and how they impact read performance 🤔

@prologic in the article they say they have a p99 of 15ms reading historical data. Which is pretty nuts.. Aside from having close to 900TB of SSD...

I suppose the p90/p50 would be higher. Right? I never remember which way that funnel goes.

Pretty sure its the average/p50 that's lower right? p90/p95 is your end tail. So if most of your latencies are sitting around ~15ms you'd expect your average to be lower, otherwise you'd have a much higher p90/p95 right? 🤔~

In any case, yeah that is impressive in and of itself, but I'm not sure what data structures and mechanisms are at play to achieve such impressive read performance? Did I miss it in the article? 🤔
