The passage you quoted has nothing to do with the paper, but about another part of the thread. Note I never said this paper wasn't about data, nor that btrfs is good wrt write amplification in the access pattern they do in this paper ; I said you might want to think whether a pattern with small writes and fsyncs in a cow filesystem is a good idea and is going to be representative of a typical user's workload. That is precisely why previously in the thread things like databases have been discussed along with the nocow chattr flag. (Yes, that means applications need to start being concious of what fs they are being run on, or at least the fedora configuration needs to do that check for them) -- Dominique _______________________________________________ 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
