More details, it seems datafusion default will not add metadata_size_hint,
we can try to add and testing it.
```rust
/// (reading) If specified, the parquet reader will try and fetch
the last `size_hint`
/// bytes of the parquet file optimistically. If not specified, two
reads are required:
/// One read to fetch the 8-byte parquet footer and
/// another to fetch the metadata length encoded in the footer
pub metadata_size_hint: Option<usize>, default = None
```
