> > The way StringView implemented this was to reuse the builder > > I don't think we want to do that here, as the builders are typed on the keys and values and so this would result in a massive amount of code generation. The kernels in arrow-select by comparison use a number of tricks to avoid this. I don't understand the codegen concern -- I am imagining that only the `DictionaryArray` Types that were actually instantiated (aka that you called `gc` on) would get code generated for them as this would be a method on `DictionaryArray` Most of the kernels in `arrow-select` take an `ArrayRef`/ `Datum` that then gets typecast down and dispatched to a bunch of pre-compiled methods (which really does generate code bloat even if you don't use those types) -- This is an automated message from the Apache Git Service.
