    In more general terms, almost every database we tested with Jepsen fails, sometimes in dozens of ways, before its test suite passes. That's how we know Jepsen is *working*! The vendor headline that comes out of that process is usually "X passes Jepsen".

    Again, YugaByte DB's Jepsen tests did not pass. They do not currently pass. Correctness issues we identified in our collaboration, mainly due to non-transactional schema changes, are still unaddressed. YugaByte and I have talked about this.
