----------------------------------
Summary: File source V2: Push data filters for file listing
Key: SPARK-30475
URL: https://issues.apache.org/jira/browse/SPARK-30475
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: Guy Khazma
Fix For: 3.0.0
Follow up on [SPARK-30428|https://github.com/apache/spark/pull/27112] which
added support for partition pruning in File source V2.
We should also pass the {{dataFilters}} to the {{listFiles method.}}
Datasources such as {{csv}} and {{json}} do not implement the
{{SupportsPushDownFilters}} trait. In order to support data skipping uniformly
for all file based data sources, one can override the {{listFiles}} method in a
{{FileIndex}} implementation, which consults external metadata and prunes the
list of files.
