----------------------------------------
Summary: Expose nested schema pruning to all V2 sources
Key: SPARK-30107
URL: https://issues.apache.org/jira/browse/SPARK-30107
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: Anton Okolnychyi
I think it would be great to expose the existing logic for nested schema
pruning to all V2 sources, which is in line with the description of
`SupportsPushDownRequiredColumns` . That way, all sources that are capable of
pruning nested columns will benefit from this.
