Pekka Enberg's personal blog at penberg.org covers systems, programming and ai. Since 2019, 12 different Hacker News readers have linked it 14 times, most often “Rearchitecting SQLite for Asynchronous I/O using io_uring [pdf]”. No feed was found, so read it on the site itself.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link Pekka Enberg's hosted papers on thread-per-core database architectures and on SQLite's synchronous design, with comments using them as background for discussions of SQLite and Turso.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
The actual reality is that I personally started the project because its synchronous architecture is holding back performance. You can read all about it in https://penberg.org/papers/penberg-edgesys24.pdf . The design is literally the next evolution of SQLite's architecture.

HN discussionThread-per-core software architectures are doing this https://penberg.org/papers/tpc-ancs19.pdf Real world examples are scylladb and Redpanda, both built on the seastar framework (C++ https://seastar.io/message-passing/ ). And for rust there is glommio https://www.datadoghq.com/blog/engineering/introducing-glomm...

HN discussionI thought the point of Turso was to offer better concurrency than SQLite currently does. A la https://turso.tech/blog/beyond-the-single-writer-limitation-... and https://penberg.org/papers/penberg-edgesys24.pdf Would be great if one of the Turso developers can clarify :)
