In the case of email, is it possible to offload everything to a mail server like Postfix? That should be able to deal with a huge queue without too many problems and without Fedora needing to write email handling code. Just send the email to the mail server and let the mail server deal with delivery. For other services, one option would be a language (Erlang? Elixir?) designed for very high levels of concurrency and reliability. That might be a better choice than Python. -- Sincerely, Demi Marie Obenour (she/her/hers) _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
