* It could very well be your query is IO/parquet bound and simd won't reduce the execution time. You could try reading the table into memory to see whether that's the case. * the normal sum kernel uses auto vectorization, so even without `simd` flag it's using some faster kernels. For most queries I didn't see an impact in DataFusion using the `simd` feature. -- This is an automated message from the Apache Git Service.
