[jira] [Created] (SPARK-37975) Implement vectorized BYTE_STREAM_SPLIT encoding for Parquet V2 support

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

             Summary: Implement vectorized BYTE_STREAM_SPLIT encoding for Parquet V2 support
                 Key: SPARK-37975
                 URL: https://issues.apache.org/jira/browse/SPARK-37975
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: Parth Chandra


Parquet V2 has a BYTE_STREAM_SPLIT encoding which is not currently directly usable by Spark (as there is no way to enable writing of this encoding). However, other engines may write a file with this encoding and the vectorized reader should be able to consume it.
A vectorized version of this encoding should be implemented
