Thousands of async calls

[eosis]

Hi Glenn,

I'm no expert in this at all, but a little searching hit upon this thread discussing FuturesUnordered:

FuturesUnordered

Here's a more or less direct translation to using Tokio and delay_for. use futures::stream::{FuturesUnordered, StreamExt}; use tokio::time::{Duration, delay_for}; use tokio::runtime::Runtime; use rand::distributions::{Distribution, Uniform}; async fn random_sleep(num: i64) -> i64 { let mut rng = rand::thread_rng(); let secs: u64 = Uniform::from(2..10).sample(&mut rng); let d = Duration::from_secs(secs); println!("--> [{}] sleep {} seconds", num, secs); delay_for(d).await; …

The example given seems applicable to you. Maybe this is a good place to start?
