FYI [~andygrove] -- I am doing some part of this in ARROW-10159 -- however, the initial implementation effectively converts DictionaryArray --> PrimitiveArray / StringArray and then uses the existing processing. To support the actual efficient processing usecase, I think significant work will be needed to add appropriate dictionary support to the arrow compute kernels
