I was unwilling to sign up to read the actual benchmark report for the comparison to cockroachdb but it jumped out at me as odd. They solve completely different kinds of problems in my experience so I’m not surprised Scylla did better in raw throughout. That’s not interesting though. It would be just as weird for cockroach to put up a benchmark showing it outperforms in distributed sql queries.
That said I’ve seen the value Scylla brings in its core value prop, replacing Cassandra. It’s real good at that.
