--------------------------------------
Summary: Improve file source V2 framework
Key: SPARK-27132
URL: https://issues.apache.org/jira/browse/SPARK-27132
Project: Spark
Issue Type: Task
Components: SQL
Affects Versions: 3.0.0
Reporter: Gengliang Wang
During the migration of CSV V2, I find that we can improve the file source v2
framework by:
1. check duplicated column names in both read and write
2. Not all the file sources support filter push down. So remove
`SupportsPushDownFilters` from FileScanBuilder
3. The method `isSplitable` might require data source options. Add a new member
`options` to FileScan.
