The OP video describes a FS based on Innodb and MySQL. It gets relatively poor performance (7-9X slower for common FS ops). However, the killer FS ops for a DB are subtree operations - 'rm -rf', 'chown -R', 'chmod -R'. In research in this field, these are the operations that get less limelight but are most important for a working system. I hazard a guess that the above implementation could still be made many times faster (maybe even 10X) by using InnoDB's native API, instead of the much slower MySQL Server SQL API. Here's an example of what you can achieve by going native - 1m ops/sec on InnoDB 8 years ago. This is the main guy (sorry Mark!) behind RocksDB implementation: http://yoshinorimatsunobu.blogspot.com/2010/10/using-mysql-as-nosql-story-for.html http://yoshinorimatsunobu.blogspot.com/2010/10/using-mysql-a...
