> We may wish to either
> * Conform the dictionary indices to reference a common dictionary
> * Concatenate indices into a new array with a common dictionary
> This is related to in-memory dictionary encoding, as you start with a
> partially-built dictionary and then add entries as you observe new ones in
> other dictionaries, all the while "rebasing" indices to consistently
> reference the same dictionary at the end
