------------------------------------
Assignee: Apache Spark
> 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
> Assignee: Apache Spark
> Priority: Major
>
> 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
