Hey all, Here is an Asio based header-only asynchronous MySQL client library called Amy (*A*synchronous *My*SQL). https://github.com/liancheng/amy In short, this library enables you to work with MySQL in both asynchronous and blocking ways. Links to examples are included in the README file. Haven't got time and energy to write comprehensive documents, though. The interesting thing is that, I wrote this library years ago as an exercise, open sourced it, and then basically forgot about it. However, recently an European developer contacted me and said that they used it in one of their game projects in production and it was "amazing". So I decided to spend some time to polish it a little bit and send it out here to see whether there are anyone else who are interested in it. Please let me know what you think about it. Thanks! Best, Cheng
