brkyvz commented on issue #25876: [SPARK-29197][SQL] Remove saveModeForDSV2 from DataFrameWriter URL: https://github.com/apache/spark/pull/25876#issuecomment-534804399 @rdblue It actually doesn't change the meaning. The only meaning change is in `insertInto`, where SaveMode only matters for an overwrite or append, and the others are meaningless. That's consistent with DataSource V1 behavior (although I agree it's weird).
