As far as I understand, Hammer2 was designed mainly for flash memory (SSD, NVMe).
Currently I am using it on a 2 TB HDD.
Imagine that a lot of files and snapshots are created and deleted and there are multiple MySQL databases there.
How will Hammer2 consistency and performance degrade over time in this use case?
Did not find information about HDDs and defragmentation in sys/fs/Hammer2/DESIGN.
