…rect when was written by some old parquet writers by disable it. (#35041) Parquet INT96 timestamp values were compared incorrectly for the purposes of producing statistics by older parquet writers, so PARQUET-1065 deprecated them. The result is that any writer that produced stats was producing unusable incorrect values, except the special case where min == max and an incorrect ordering would not be material to the result. PARQUET-1026 made binary stats available and valid in that special case.
