Library Guide: Building LogicalPlans #7306
Description
Activity
@alamb I checked the previous @andygrove PR and it seems like we have a good setup. I read the docs, and noticed they lack a paragraph on how to translate the LogicalPlan into Physical Plan .
What do you think we should do? I can add that paragraph, but maybe we also want to link the examples? What else do you think it's needed to close this

Those both sound like excellent ideas to close off this issue. Thank you @edmondop
I noticed that the original work from @andygrove referred examples in the docs and these seems to be pretty "unique" in the sense that no other doc page seems to take this approach , see https://github.com/apache/datafusion/tree/main/docs/src
What do you think about moving those into examples and linking them from the docs? Do we have a preprocessor macro to includes the Rust code in a markdown upon compilation, or maybe to ensure that the embedded snippets compile and execute correctly ?
I think @andygrove started on a pre-processor that extracted the markdown and tested it here #7956
Maybe we can revive that idea

on Aug 16, 2024 I've added a first draft to the doc. Let me know if you would look for a more sophisticated example.

Part of #7014
If we want to have DataFusion used as the core of many new systems, we need it to be as easy as possible for someone to get their idea working on top of DataFusion.
Thanks to @tshauck we now have a basic Library Users Guide ❤️ and this ticket describes expanding it out
