So, in general, I understand there is lots of stuff going on in Scylla that does distinguish it, at least from Cassandra. There is the user space networking logic for IO. However, a lot of the IO overhead with disk, for example.

Given that i/o bandwidth and throughput continues to increase, processor frequency isn't, and core counts are going up, it's prudent to design a system that can take advantage of this.
- cbsmith 11y agoYeah, and a 4x SSD RAID configuration is kind of overkill in the extreme for most Cassandra set ups. I'm sure there is a way to set up IO subsystems so that Cassandra becomes a huge bottleneck, but that's a pretty specialized context.
