Does anybody else think the salaries are a little high? Perhaps the sample size is skewed? I'm somewhat senior in software engineering, but I literally don't know a single person making over 200k. Nada. Not one. I also don't know any college grads who started making 150k. That seems absurd, unless you're only looking at certain companies and top performers or something.
Please make sure you understand log replication and go through fire drills for the list of things that can go wrong with bi-directional replication. The last thing you'll want to do is deploy this into production and wing operations as you go.
