How many transitive dependencies is the right number for a database?
A non-obvious issue is that database engines have peculiar requirements for how libraries are designed and implemented which almost no conventional library satisfies. To make matters worse, two different database implementations may have different requirements in this regard, so you can't even share libraries between databases. There are no black boxes in good database engines.
Looking at the dependencies list (https://gist.github.com/tisonkun/06550d2dcd9cf6551887ee6305e...) I see plenty of reasonable things like:
* Base64/checksum/compression encoding libraries
* Encryption/hash libraries
* Platform-specific bindings (likely conditional dependencies)
* Bit hacking/casting/zero-copy libraries like bytemuck, zerocopy, zero-vec, etc.
* "Small"/stack allocated data structure libraries (smallvec, tinystr, etc.)
* Unicode libraries
There are certainly things that would add bloat too, but I think it's silly to pretend like everything here is something a database engine would need custom implementations of.
Combine this with the challenge of implementations being async, non-allocating, compatible with explicitly paged memory, etc and it generally becomes worth the effort.
You'll find more libraries used at the periphery for integration and compatibility where it matters less but not in the core.
I'd rather an author pulls in a tinyvec/serde than tries to make a bespoke implementation.
That’s fine, I have not objection to hot takes, but don’t conflate your limited experience with reality.
I get it that you work on a geospatial database and understand this field better than I do, but why so rude and dismissive? Work on that.
In the case where the answer is "zero", then that means that one does not actually need a package manager at all, in which case the features of the package manager are not relevant to the choice of language. This would imply that the parent commenter has no need to reject Rust.
