I've read some of your High Performance MySQL series articles, and they were really interesting and informative, so I was glad to see you highlight this book since I've found a lot of people out there rave about it recently. I've only just started this series and I'm sort of excited to read the rest. Thank you for your efforts.

thank you for the great article I liked the example of sidekiq and I will suggests that you highlight the parts of the article that you put from your experience in a different format, so it is easier for the one who already just read the chapter to find your comments which doesn't exist in the book
