> blazingly fast

I’m going to need to see a citation for that. Last I checked, it was being beaten by Apache Spark in non-memory constrained scenarios [0]. This may be “blazingly fast” compared to Pandas or something, but it’s still leaving a TON of room on the table performance-wise. There’s a reason why Databricks found it necessary to redirect their Spark backend to a custom native query engine [1].
