Suggest watching the Tigerbeatle video link in the article. There they discuss bitrot, "fsync gate", how Postgres used fsync wrong for 30 years, etc. It is very interesting even as pure entertainment.
Just to emphasize again that this blog post here is really quite different, since it does not fsync and breaks durability.
Not what we do in TigerBeetle or would recommend or encourage.
