Maybe this question is not relevant for Traefik, but with nginx and haproxy they support hitless reloads (https://www.haproxy.com/blog/hitless-reloads-with-haproxy-howto/), in order not to lose a single request during config reloading. How does this relate to Traefik? Or is this a non-issue with Traefik? I guess my actual question is: is it possible to lose requests with Traefik during config updates?
It's a "non-issue" with Traefik because the reload of configuration is made by a switch of the configuration in memory.
So reloading is done without restarting the process and without closing the current connections.
Cool, thank you for the confirmation!
