Can you accelerate queries when your data is *partially* sorted (and e.g. you don't want to have to resort it). Yes. Qi Zhu and I explain how in: datafusion.apache.org/blog/2026/07...

Whenever I think we can't possibly make filtering faster in Arrow / Rust, I am proved incorrect. Huge kudos to @ClSlaid for squeezing out even more performance github.com/apache/arrow...
We recently hit 5 digit issue mark in arrow-rs. Admittedly this isn't as cool as before LLMs but it is still neat 🤩 github.com/apache/arrow...
A new milestone: @duckdb.org is following DataFusion 😎 github.com/duckdb/duckd... Admittedly this is somewhat ClickBenchmaxxing, but I think it is evidence that analytic engine performance is converging over time (we are in a race to the bottom on performance), accelerated by LLMs
