I think the idea is sound in principle, but needs a concrete API proposal. I'm not sure the proposed builder API makes sense, as the typing for nested types like ListBuilder and DictionaryBuilder is not what we want here, and they can't easily be type erased. We also ideally want to avoid overly bloating the arrow-array crate with kernel logic. _This isn't even touching on the fact these kernels don't use the builders for performance reasons._ I think we'd need to introduce a new type-erased MutableArray abstraction or something, potentially replacing the rather problematic MutableArrayData. The only remaining challenge concerns dictionaries, as the output dictionary needs to be computed up front. Simply not supporting dictonaries could potentially be a valid workaround though. -- This is an automated message from the Apache Git Service.
