Congratulation!

The scenario if fully valid (if exclude transformation, that does not happen so often). May be not all steps you made, but that or another part is used for for real data recovery.

Well, I finally figured out what the tricksy obfusication. Thankfully I don’t think any real databases would apply transformations like that without them being known when you’re trying to recover data.

I’m curious if this scenario is based on an actual client experience.

Thanks to Vadim for putting this together and offering the incentive. I knew *about* innodb recovery techiniqes before, but thankfully have never had to use them. This was an excellent practice exercise, and I highly recommend everyone try to solve it since it will require you to learn a few tricks and skills that will really come in handy if you ever *have* to do it. I thought I knew innodb pretty well before, but I found that there is always much more to learn.
