new blog post on Calcite
Hello all,
I wrote a new blog post about some of Calcite's internals: https://www.feldera.com/blog/constant-folding-in-calcite
I would appreciate a review. When/if people think it's fine, I will add a link to it from the site.
Thank you,
Mihai

Great post Mihai, very didactic!
PS: I agree with Dmitry about improving the mobile version.

Very nice blog post Mihai! The fact that it starts from a simple test
case and ends-up with a deep dive into runtime internals and code
generation makes it a valuable resource especially for new
contributors in this area. I also like the historical part about LINQ
and the relevant citations as I wasn't familiar with those.

Nice blog post! I really enjoyed reading it. I just have one suggestion,
and it's not about the article: fix mobile version

Looks great.
You are missing a space before “ReduceExpressionsRule”.
I love how you have written a practical set of steps for people to use/extend Calcite. (Or indeed people assisted by AI. I can imagine telling Claude ‘Go read Mihai’s blog post, then …’.)
The sidebar about LINQ/linq4j/DryadLINQ is fascinating. It adds color and background to this post, but it would also work as a standalone post. If I were you, I would publish the post now as is but come back in a week or two and factor it out — same content, maybe expanded a little. (If it isn’t obvious, Morel is another member of the family tree that includes LINQ.)
