**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> Currently the zip kernel makes use of `MutableArrayData`. This will work well when the mask contains long runs of true or false values, and when the inputs are not scalar. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> It is conceivable that constructing an input for the interleave kernel is always faster, but it is also possible a hybrid approach that does the following might be possible: * Count bits in mask * If less than some threshold set or unset use MutableArrayData * Otherwise use interleave kernel This will involve writing good benchmarks to assess the impact of any change **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.
