--------------------------------

             Summary: Support Parquet v2 data page encodings for the vectorized path
                 Key: SPARK-36879
                 URL: https://issues.apache.org/jira/browse/SPARK-36879
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 3.3.0
            Reporter: Chao Sun


Currently Spark only support Parquet V1 encodings (i.e., PLAIN/DICTIONARY/RLE) in the vectorized path, and throws exception otherwise:
{code}
java.lang.UnsupportedOperationException: Unsupported encoding: DELTA_BYTE_ARRAY
{code}

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
