Writing a book: is it worth it? — Martin Kleppmann’s blog

My book, Designing Data-Intensive Applications, recently passed the milestone of 100,000 copies sold. Last year, it was the second-best-selling book in O’Reilly’s entire catalogue, second only to Aurélien Géron’s machine learning book. Machine learning is obviously a hot topic, so I am quite content with coming second to it!

To me, the success of this book was totally unexpected: while I was writing it, I thought that it was going to be a bit niche, and I set myself the goal of selling 10,000 copies over the lifetime of the book. Having passed that goal tenfold, this seems like a good opportunity to look back and reflect on the process. I don’t want to make this post too self-congratulatory, but rather I will try to share some insights into the business of book-writing.

Is it...

Is it financially worth it?...
