mbutrovich opened a new issue, #15763: URL: https://github.com/apache/datafusion/issues/15763
### Describe the bug The logic that coerces timestamps to a different resolution iterates through fields and uses their key in the Parquet schema as a key to match against the Arrow schema. https://github.com/apache/datafusion/blob/66a7423a4e9116d30d7defc56216f4e7a7bcf7ac/datafusion/datasource-parquet/src/file_format.rs#L586 However, this is insufficient (consider a schema with structs each with an `id` field) to disambiguate nested fields. I think we might need a combination of Parquet ColumnDesc's path and a normalized Arrow schema to fix the mapping. ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
