Show HN: InnoDB_rs – InnoDB Recovery Toolkit in Rust

I recently had the "opportunity" to recover a database from being accidentally `rm -rf`'ed. In the process decided the best route is to implement InnoDB storage format and scan the disk for any and all record we can still find.

Configuring innodb file per table was pretty common years ago when I last worked with MySQL. I thought the entire file gets deleted if you nuke the table. This would be for the default config with a single innodb file right? To remove some tombstones.

Yeah this tool was written to help recover from accidentally `rm -rf` the entire mysql data folder. The `page_extractor` you can feed it the whole block device and extract all InnoDB pages that has checksum that match.
