Interesting notes, thanks. I was struggling with such books that compress a complex idea in a couple of sentences, so I'm always trying to explain as detailed as possible. Though understanding that there is a broad audience who likes the opposite (succinct explanations), I wrote disclaimers to secure me just in case. So, read the disclaimers one more time, that's my only excuse for such long and boring discussions :)
Thank you very much!
I don't really get upset for critics, it helps a lot to produce the next good work (noting previous complains).
However, hearing some really positive feedback is always motivating to spend more time on knowledge sharing. Thanks again!
:D noted, thanks. I just hate those part 1, part 2, part N articles, so tried to put all in one. However, done just 40% of the initial plan, so some new looong article will be published sometime in the future.
The point of example is to show that graphs (for Airbnb case - trees) are a good fit. Modern sql database should be enough, but just because it has strong indexing, which is mostly implemented using B-trees, which are again graphs. So Airbnb example takes the reader to balanced binary trees (though it seems long reading).
