[C++] Support reading non-dictionary encoded binary Parquet columns directly as DictionaryArray

    Details

      Description

      If the goal is to hash this data anyway into a categorical-type array, then it would be better to offer the option to "push down" the hashing into the Parquet read hot path rather than first fully materializing a dense vector of ByteArray values, which could use a lot of memory after decompression
