             Summary: Implement vectorized  DELTA_BYTE_ARRAY and DELTA_LENGTH_BYTE_ARRAY encodings for Parquet V2 support
                 Key: SPARK-37974
                 URL: https://issues.apache.org/jira/browse/SPARK-37974
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Parth Chandra


SPARK-36879 implements the DELTA_BINARY_PACKED encoding which is for integer values, but does not implement the DELTA_BYTE_ARRAY encoding which is for string values. DELTA_BYTE_ARRAY encoding also requires the DELTA_LENGTH_BYTE_ARRAY encoding. Both these encodings need vectorized versions as the current implementation simply calls the non-vectorized Parquet library methods.
