**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** As part of https://github.com/apache/arrow-rs/issues/6002, @adriangb @etseidl and myself are working to improve the APIs to work with ParquetMetaData The main usecase is to store this metadata "out of band" (aka somewhere that is not interleaved with the Parquet data itself). Part of storing such metadata often involves modifying existing ParquetMetaData before restoring For example, one might want to remove the page index structures to save space. At the moment it is awkward to modify ParquetMetaData (you have to re-create it from its constitutent fields, and there is no way to avoid clone'ing) **Describe the solution you'd like** I would like some API to modify a ParquetMetaData **Describe alternatives you've considered** I propose a `ParquetMetaDataBuilder` that follows the model of [`RowGroupMetaDataBuilder`](https://docs.rs/parquet/latest/parquet/file/metadata/struct.RowGroupMetaDataBuilder.html) I added a simple one as part of trying to write a test in: https://github.com/apache/arrow-rs/pull/6463 which I plan to propose as a real API **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
