comprehensive-rust VS datafusion

Thanks! We do include speaker notes on some pages (but not yet all[1]). We would love to expand this and PRs are very welcome for this :-)

I think videos will end up being made by someone other than me since I feel it takes too much effort when you don't have the right setup already. We have an issue and I'll update it as soon as I hear more about videos.[2]

A bit more detail: we've been expanding our Rust training at Google over the last year. We've now had more than 500 Googlers go through Comprehensive Rust and they tell us that they really like it — also when we ask them again three months later :-)

The post is a huge Thank You! to the many people who have helped with the course, both inside and outside of Google. More than 30 Googlers (who already knew Rust) have picked up the course and taught it around the world.

People have used the material for [university classes](https://mo8it.com/blog/teaching-rust/) and there will soon be [online classes](https://twitter.com/mrtngslr/status/1696601520412783052) as well. I hope it will become a good resource for people to teach Rust in many different contexts!

Pull requests are always welcome, the whole thing is open source: https://github.com/google/comprehensive-rust/.

Yes, I would love to have more contributors to https://github.com/google/comprehensive-rust and https://github.com/google/mdbook-i18n-helpers!

That's done with a bit of JavaScript. It's not super elegant... I would love to have someone with current JavaScript skills improve it :D

Python's Substrait seems like the biggest/most-used competitor-ish out there. I'd love some compare & contrast; my sense is that Substrait has a smaller ambition, and more wants to be a language for talking about execution rather than a full on execution engine. https://github.com/substrait-io/substrait

We can also see from the DataFusion discussion that they too see themselves as a bit of a Velox competitor. https://github.com/apache/arrow-datafusion/discussions/6441

Agree, substrait is a really cool project! Related: if you like substrait you might want to check out datafusion too. The project is a query execution engine built on top of Apache Arrow (with SQL parser, query planner & optimizer, execution engine, extensible user defined functions, among others) and it implements a substrait provider and consumer: https://github.com/apache/arrow-datafusion/tree/main/datafus...

The draft contains some preliminary benchmark results, comparing it to DuckDB.

Apache Arrow is a pretty common memory structure these days. Datafusion is an open query engine built in Rust started by Andy Grove.

DuckDB is a great piece of software if you are

If you are looking for a query engine implemented in a safe language (Rust) I definitely suggest checking out DataFusion. It is comparable to DuckDB in performance, has all the standard built in SQL functionality, and is extensible in pretty much all areas (query language, data formats, catalogs, user defined functions, etc)

Problem comes when you want to do this inside an async context since we couldn't block an async task. https://users.rust-lang.org/t/sync-function-invoking-async/43364/6 You might need to do it in another runtime/thread. It is not recommended to do this, but sometimes it is unavoidable while implementing a third-party trait. https://github.com/apache/arrow-datafusion/issues/3777 However, I believe this isn't a problem particular to tokio, or any specific runtime.
