Use HDD for data storage, SSH for metadata

Our storage servers have 12 hdd's for actual data, and 2 NVMe ssd's for metadata. How would I configure RustFS to storage metadata on the ssd's so metadata operations don't have to hit the (relatively slow) hdd's?

In Ceph its common practice to add ssd's to servers with hdd storage to store WAL and metadata on, and I'm wondering how to get similar results with RustFS.

This feature is not supported. Our metadata and data are stored on the hard drive.

Right, that was my conclusion as well. Thank you.

Are there plans to change this in the future? Or does it matter less because of architectural differences between Ceph and RustFS?

Garage has a similar design: SSD for metadata, HDD for storage.
I'm testing Garage and RustFS and well... something else.

Mixing metadata and storage doesn't seem like a good idea at all. Even on ZFS you can split it.
