aws-sdk-rust VS datafusion

The AWS SDK for Rust contains one crate for each AWS service - you can check them out here.

> What kind of plans for support of Rust's evolving async ecosystem?

We were hoping async-function-in-trait would land before GA, however, we have a plan to add support in a backwards compatible way when it's released.

> Any particular reason why the public roadmap does not show the columns similar to "Researching", "We're Working On It" like the other similar public AWS Roadmaps?

Our roadmap has unfortunately been in a state of disrepair for some time. We're hoping to get it cleaned up and accurate post GA.

> Would be nice to have fully working examples on Github, for most common scenarios across most AWS services. This is something that historically AWS SDKs have been inconsistent on. Just a request not really a question :-)

There are lots of examples here [1], some simple, some quite complex. If there's something you have in mind, please file an issue! Having great examples is one of our priorities.

There’s a pretty nice example of this in the aws rust sdk here.

The official AWS Rust SDK still seems to be a work in progress(developer preview) with a warning to not use it in production.

i'm using https://github.com/awslabs/aws-sdk-rust heavily and was wondering if there was a more specific community (subreddit, Discord server, etc) of Rust x AWS developers?

Only relevant search result was this github issue, which didn't really solve the problem.

I went on rusoto just because aws-sdk-rust says at the beginning of the readme:

Official libraries for major cloud vendors will definitely boost Rust's adoption. aws-sdk-rust is still in 'developer preview', but it's getting there.

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.

https://github.com/apache/arrow-datafusion/issues/6782

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.
