We don't technically support any of the others.

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. -- You received this message because you are subscribed to the Google Groups "OSv Development" group.

ScyllaDB on OSv?
Given that ScyllaDB uses seastar that can run on OSv is it possible to run ScyllaDB on OSv? I have not found anything on scyllaDB site ? 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? -- You received this message because you are subscribed to the Google Groups "OSv Development" group.
