cloud-fan commented on issue #26297: [SPARK-29665][SQL] refine the TableProvider interface URL: https://github.com/apache/spark/pull/26297#issuecomment-561950169 It's hard to write a stub implementation. The API change is too big. Previously file source v2 implements schema/partition inference in `XYZFileTable` , now it needs to be moved to `XYZDataSourceV2`. I've open https://github.com/apache/spark/pull/26750 to give up the refactor and only do the necessary change to accept user-specified partitioning in `TableProvider`. Please take a look, thanks!
