Send 1 mln requests - strategy - Lemmy.World

One needs to send 1 mln HTTP requests concurrently, in batches, and read the responses. No more than 100 requests at a time. Which way will it be better, recommended, idiomatic? * 1) Send 100 ones, wait for them to finish, send another 100, wait for them to finish… and so on * 2) Send 100 ones. And then keep adding new ones into the pool as requests in the pool finish. “Done - add a new one. Done - add a new one”.
