问题
We are using Locust to for load testing rest api services behind elastic load balancing. I came across this article regarding load balancing and auto scaling, which is something we are testing.
Locust is using python-requests which is using urllib3, so my question is if python-requests does a dns query for every connect, and if not, is it configurable?

Locust is using python requests that is using urllib3 that is using socket.getaddrinfo which has DNS caching disabled according to this SO thread (given that your test machine runs linux).
