### Feature Request / Improvement In Iceberg's TableMetadata JSON file, all historical snapshot information, schema information, and SortOrder information are stored in a single file. If there is a large amount of historical data, loading this JSON file can take a considerable amount of time. If the information corresponding to each ID is split and written into separate files, and the TableMetadata JSON only retains pointers to these files, loading information on demand, then performance should be significantly improved. ### Query engine None ### Willingness to contribute - [ ] I can contribute this improvement/feature independently - [ ] I would be willing to contribute this improvement/feature with guidance from the Iceberg community - [ ] I cannot contribute this improvement/feature at this time -- This is an automated message from the Apache Git Service.
