Summary: Refactor DataSourceScanExec code to
Key: SPARK-38999
URL: https://issues.apache.org/jira/browse/SPARK-38999
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.3.0, 3.2.2, 3.4.0
Reporter: Utkarsh Agarwal
Currently the code for `FileSourceScanExec` class, the physical node for the
file scans is quite complex and lengthy. The class should be refactored into a
trait `FileSourceScanLike` which implements basic functionality like metrics
and file listing. The execution specific code can then live inside
`FileSourceScanExec` which will subclass `FileSourceScanLike`.
