Jiayi-Wang-db opened a new issue, #622: URL: https://github.com/apache/parquet-format/issues/622
This issue proposes a modular footer layout that separates schema, column placement, statistics, and other metadata into independently addressable and decodable modules. This lets readers fetch only the metadata required for schema resolution, I/O planning, and pruning, reducing both I/O and decoding time compared with parsing the complete `FileMetaData` structure. The full motivation, format, compatibility considerations, and prototype results are described in the [proposal](https://docs.google.com/document/d/1xN4Nqh-fh-eH-cUz9e6Rqs_gPXRBKUh4s29EzX_NU8M/edit?usp=sharing). This issue is for discussing the overall direction. -- This is an automated message from the Apache Git Service.
