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