arrow-datafusion VS ht

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.

No need to use curl, make HTTP requests great again with https://github.com/ducaale/xh

Except when you actually enjoy things being fast. For example, HTTPie easily adds 0.5-1s delay to every request because it's written in Python, especially on the first invocation. xh (https://github.com/ducaale/xh), on the other hand, starts immediately because it's written in Rust. I very much like this trend.

HTTPie is great and was a big improvement for me over cURL.

However, I ended up switching to xh[1] as it's significantly faster and I prefer its output.

https://github.com/ducaale/xh

No, but unless portability is a concern or you're massively familiar with curl, you might want to consider xh. It's much more intuitive.

xh

wget on the other hand, automatically converts the ñ to UTF-8 hex and resolves the link perfectly.

I've searched the curl manpage and couldn't find a way to solve this. Please help.

I'm having to use `xh --curl` [1] to "fix" the links before I pass them to curl.

Very nice, you should add xh to the User-Agents though.

While not a rewrite - one recent tool for making http requests which i quite enjoy is:

https://github.com/ducaale/xh

It's basically python httpie rewritten in rust. my only gripe is that i keep forgetting that it exists - and that "xh" is for http and "xhs" is for https.

So i frequently end up with curl anyway:)
