Do you use btrfs for anything serious?

Question

Btrfs is 15 years old. It seems to be the Linux ecosystem response to ZFS.But is it ready for production? If not, will it ever be? Are there alternatives for a modern production ready file system for Linux with compression, deduplication, integrity checks, and so on?I am curious to know who uses btrfs for anything serious and business critical.Please share your experiences.

i use it personally, but found reiserfs works better for me on spinning disks - both space and speed. ( lots of small files ) - btrfs, even with compression uses more spacefor normal workloads, ext4 is fine for me
