ah, so something like... if the primary ordered transaction 3 < transaction 1, but transaction 2 observes only transaction 1 on the read-only secondary potentially because the secondary orders transaction 1 < transaction 3?

"I think what's going on here is that a read-only transaction against a secondary can observe some transaction T, but also miss transactions which must have logically executed before T." i was intuitively wondering the same

Scylla (and Cassandra) provides cluster-level replication. Even with only local NVMes, a single node failure with loss of data would be tolerated. But relying on "ephemeral local SSDs" that nodes can lose if any VM is power-cycled

That's good observation. We've spent a lot of time on our control plane which handles the various RAID1 failure modes, e.g. when a RAID1 degrades due to failed local SSD, we force stop the node so that it doesn't continue to
