I generally think micro services are a bad idea, partly because it’s so useful to share data and code implicitly.

Somewhat more macro services can make sense, especially when each team owns a service. That’s also when sharing data is harder.

Yep. The only example I have from my career was a team having their own read replica and ETLing that to Hadoop. The schema hadn’t changed in 10+ years, so it wasn’t even considered a real risk.
