    Description

      Currently Spark only support Parquet V1 encodings (i.e., PLAIN/DICTIONARY/RLE) in the vectorized path, and throws exception otherwise:

      java.lang.UnsupportedOperationException: Unsupported encoding: DELTA_BYTE_ARRAY
      

      It will be good to support v2 encodings too, including DELTA_BINARY_PACKED, DELTA_LENGTH_BYTE_ARRAY, DELTA_BYTE_ARRAY as well as BYTE_STREAM_SPLIT as listed in https://github.com/apache/parquet-format/blob/master/Encodings.md
