**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Most kernels evaluate the operations on all values regardless of whether it is null or not. However, if the batch consists of mostly nulls, it may be faster to skip the null values. We can utilize the `try_for_each_valid_idx` function added recently by @tustvold **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> At a certain threshold fraction of null values (based on benchmarking) we can use the `try_for_each_valid_idx` approach used by the checked variants of the kernels to speed up operations on batches with mostly nulls. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
