Thank you for the approval @Dandandan . but it doesn't seem like the benchmarks ran correctly. Could you please trigger it again and perhaps even toch tpcds and other relevant queries please?

Dandandan · 2026-04-17T07:10:26Z

+            offsets.push(all_values.len() as i32);
+        }
+
+        let values_array = Arc::new(PrimitiveArray::<T>::from_iter_values(all_values));


Suggested change

let values_array = Arc::new(PrimitiveArray::<T>::from_iter_values(all_values));

let values_array = Arc::new(PrimitiveArray::<T>::new(ScalarBuffer::from(all_values), None));

This is faster as well @coderfender (avoids a copy).
