Hi,
During 2020 Open Source Summit North America, Josef shared some
details about how btrfs excels in production at Facebook. And where
the problems were.
I cannot find the recording, but the write up is at Linux Weekly News:
https://lwn.net/SubscriberLink/824855/e601d11e157e1b4a/
I highly recomend it. Also, consider subscribing to LWN – it's an
invaluable source of high quality writing.
