xushiyan opened a new pull request, #599:
URL: https://github.com/apache/hudi-rs/pull/599
## Description
Refactors base-file reads by moving Parquet-specific I/O out of `Storage`
into a new `BaseFileReader` abstraction and `ParquetBaseFileReader`.
`Storage` now stays focused on object-store access, while schema resolution,
footer stats, file-group streaming, and stats estimation call the Parquet
reader explicitly.
The dispatch helpers on `BaseFileFormatValue` support config-first and
extension fallback for Parquet and HFile, with HFile kept on the metadata-table
reader path.
## How are the changes test-covered
