[C++] Implement functions to conform unequal dictionaries amongst multiple Arrow arrays

    XMLWordPrintableJSON

    Details

      Description

      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
