**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Currently `metadata_size_hint` passed to `ParquetExec` has the following issues: - **single value:** It is a single value, but a single `ParquetExec` may contain multiple files. These files may require different hints. - **serialization:** The value is dropped during protobuf serialization. Now these two issues are unrelated, but it feels like fixing both in one go makes sense. **Describe the solution you'd like** Move `metadata_size_hint` to `FileScanConfig::file_groups` > `PartitionedFile`: https://github.com/apache/arrow-datafusion/blob/d11820aa256284f9a817c7b699a548f9c3e1c399/datafusion/core/src/datasource/listing/mod.rs#L51-L64 **Describe alternatives you've considered** Leaving the status quo. **Additional context** \- -- This is an automated message from the Apache Git Service.
