Martin Kleppmann's Strange Loop talk on database transactions, covering why they were dropped by NoSQL, their reputation for being slow, and newer algorithms that make serializable transactions perform and scale. It touches on consistency, linearizability and the CAP theorem.
Why Hacker News points people here: Recommended as a compact preview of Kleppmann's data systems material, including from his book on the subject.

Condensed glimpse of Kleppmann's book content on data systems
It's great. Incredibly dense with useful information and it just blows my mind how much knowledge Martin has about the topic. I recommend watching this talk from him to give a little glimpse of the book: this video This is just about a little part of one of the chapters.
Cited for the 'invert the database' idea
I mean, I hear you that people do that and it does allow you to avoid needing distributed transactions. When you're stuck with an underlying NoSQL database without transactions, this is the best thing you can do. This is the whole "invert the database" idea that ends up with [1]. I'm arguing that that usage pattern was painful and that if you can have horizontally scalable transaction processing and a stream of events due to committed transactions downstream, you can use that to power correct and easy to reason about materializations as well as asynchronous task processing. Transact to change state. React to state changes. Prosper. [1] this video
