>                 Key: SPARK-27627
>                 URL: https://issues.apache.org/jira/browse/SPARK-27627
>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.0.0
>            Reporter: Gengliang Wang
>            Priority: Major
>
> Background:
> The data source option "pathGlobFilter" is introduced for Binary file format: https://github.com/apache/spark/pull/24354 , which can be used for filtering file names, e.g. reading "*.png" files only while there is "*.json" files in the same directory.
> Proposal:
> Make the option "pathGlobFilter" as a general option for all file sources. The path filtering should happen in the path globbing on Driver.
> Motivation:
> Filtering the file path names in file scan tasks on executors is kind of ugly. 
> Impact:
> 1. The splitting of file partitions will be more balanced.
> 2. The metrics of file scan will be more accurate.
> 3. Users can use the option for reading other file sources.
