kimtkyeom commented on issue #27888: [SPARK-31116][SQL] Fix nested schema case-sensitivity in ParquetRowConverter URL: https://github.com/apache/spark/pull/27888#issuecomment-599470082 > That's a correct behavior in `case-sensitive mode`, isn't it? Given the original schema `NAMED_STRUCT('lowercase', id, 'camelCase', id + 1) AS StructColumn`, `StructColumn` is matched and `LowerCase` and `camelcase` is not matched. So, the result is a struct with two `null` fields. @dongjoon-hyun Ah got it. There is no failure except above case. (BTW, I think materialization of rows with nested column where non-matched column would be consistent regardless of file format, but that is out of this PR scope.)
