Given that ScyllaDB uses seastar that can run on OSv is it possible to

If no are there any plans do make it possible? If yes would there be
any advantage of running scylladb on top of OSV performance-wise?
Right now OSv lacks a good aio-enabled filesystem. ZFS is designed to
provide clever caching and file management tools (ARC, snapshots) while
ScyllaDB wants to do its own caching and DMA file data directly from
disk using AIO.
Given a good asynchronous filesystem, a port of seastar/scylladb to OSv
could deliver great results, as the costs of doing I/O would decrease.
We'd also want to run OSv on bare metal for this, not just on
virtualized environments. With DPDK driving networking, and with
storage using standardized NVMe and AHCI interfaces, this is not so hard.
There are no plans to do this in the near future, though.
