[GitHub] [spark] clee704 commented on pull request #28450: [SPARK-31639] Revert SPARK-27528 Use Parquet logical type TIMESTAMP_MICROS by default

   Can someone explain why we reverted to INT96? I read https://issues.apache.org/jira/browse/SPARK-31085 but want to know how the discussion happened. To me the cost of breaking the API (INT96 by default) seems smaller than the benefit (better performance for reading, for users not using Hive/Presto).
