sqllogictest VS zig

That specific SQLite test suite (one of four [1]) has loads of generated SQL functions, and a long tail of more complex hand-written tests. That 95% of the test suite will be mostly generated queries that follow the same basic pattern of joins and projections with basic arithmetic and comparisons. See for example [2] and [3].

The generated tests are not designed to test a wide breadth of features of the SQL language, and passing them with a simple engine is very doable. A lot of the value of these tests is that the sheer volume of queries tends to find obscure problems in optimizers that would not easily surface otherwise. That is of course not a problem in a simple engine that does not have an optimizer.

It's "Zig" not "Zag". https://ziglang.org/ Zig is under heavy development, but there's a single page https://ziglang.org/documentation/0.12.0/ that is a reasonably comprehensive source of truth about the current state of the language.

There is an issue proposing this approach: https://github.com/ziglang/zig/issues/4284

When writing code in a scripting language, sometimes you need that extra bit of performance (or maybe an async feature from Zig).

NodeJS is by no means a slow runtime, it wouldn’t be so popular if it was. But compared to Bun, it’s slow. Bun was built from the ground up with speed in mind, using both JavascriptCore and Zig. The Bun team spent an enormous amount of time and energy trying to make Bun fast, including lots of profiling, benchmarking, and optimizations.

ntdll.dll!RtlUserThreadStart()

There are valid reasons to use APIs from NTDLL. Where I disagree with zig#1840 is the idea that it is always better to use NTDLL versions of API. Every other software ecosystem uses the standard Win32 APIs and diverging from that without a good reason seems like a good way to have unexpected behavior. One concrete example is most users and programmers expect Windows to redirect some file system paths when running on WOW64. But this is implemented in Kernel32, not ntdll.
