Interesting! From his post,
Mikhail advised me to use balanced trees instead of extensible hashing
And
I never told Mikhail that Oracle had tried implementing a filesystem using balanced trees, and its performance was terrible leading to most insiders in the industry concluding that balanced trees performed poorly for filesystem File size patterns.
Of course, that filesystem exists today as btrfs.
Just ask ChatGPT; it’s better than humans at proving its humanity with these stupid things.
