Hi @alamb - I've used `datafusion_aggregate_bench` to run up a comparison with `master` and the ratios are coming up at 0.99 so there's nothing significant in the way of a performance improvement yet. Could you please help me understand your suggestion: > am not sure how well the compiler will be able to optimize given a has nulls parameter has_nulls -- it might need to be hoisted out of this loop (the call to all here) I'm not sure what this means. Are you perhaps suggesting that I use an index lookup of `null_information` rather than using `zip`? -- This is an automated message from the Apache Git Service.
