A comment on Improving distributed caching performance and efficiency at Pinterest. Parent comment
As an anecdote, I've worked at a scale up that handled ~20M HTTP(S) req/min on their service mesh.
The rule of thumb was that our Redis cache layer would have 10x the number of HTTP request, so 200M req/min.
Note that I'm using minutes, not seconds on the units. But it wouldn't surprise me that Pinterest handles 60x the load that we had back then.
