gengliangwang commented on issue #24327: [SPARK-27418][SQL] Migrate Parquet to File Data Source V2 URL: https://github.com/apache/spark/pull/24327#issuecomment-498002979 @dongjoon-hyun I think one possible solution to address your concern without bringing in regressions is to change the filter pushdown API as mix-in trait of `Scan` instead of `ScanBuilder`. But I think that's beyond the scope of this PR. Unless there is a clear solution now, I hope we can move on.
