# frozen_string_literal: true

# Unicorn terminates any request which runs longer than 60 seconds.
# Puma doesn't have any timeout mechanism for terminating long-running
# requests, to make sure that server is not paralyzed by long-running
# or stuck queries, we add a request timeout which terminates the
# request after 60 seconds. This may be dangerous in some situations
# (https://github.com/heroku/rack-timeout/blob/master/doc/exceptions.md)
# and it's used only as the last resort. In such case this termination is
# logged and we should fix the potential timeout issue in the code itself.
