--------------------------------
Summary: Implement lazy decoding for the vectorized Parquet reader
Key: SPARK-36528
URL: https://issues.apache.org/jira/browse/SPARK-36528
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.3.0
Reporter: Chao Sun
Currently Spark first decode (e.g., RLE/bit-packed, PLAIN) into column vector
and then operate on the decoded data. However, it may be more efficient to
directly operate on encoded data (e.g., when the data is using RLE encoding).
