> fully managed HA cluster

This is where Suspension of Disbelief stops for me — I've been taught by years of Jepsen analyses that "HA" really doesn't exist, especially in the SQL database world, and especially if there is a big company behind with lots of big complicated buzzwords.

What you usually get is single master replication, and you get to pick up the pieces if the master dies.

Jepsen doesn't work through databases in any kind of order as far as I can tell, and they haven't done an analysis of Oracle or many other popular databases. So I wouldn't take that as a representative sample.

RAC clusters are multi-write-master and HA. The drivers know how to fail over between nodes, can continue transactions across a failover and this can work even across major version upgrades.

I wonder if the clause in the Oracle license that prohibits publishing benchmarks and other studies could be to blame for Jepsen having not investigated..?
