Sorry for late reply because I'm a bit busy these days. I found a problem that bloom filter is not trival, it might enhance the performance, and might not. Should I add an `use_bloom_filter` options in `ParquetFragmentScanOptions` ?
```c++
/// \brief Per-scan options for Parquet fragments
class ARROW_DS_EXPORT ParquetFragmentScanOptions : public FragmentScanOptions {
public:
ParquetFragmentScanOptions();
std::string type_name() const override { return kParquetTypeName; }
/// Reader properties. Not all properties are respected: memory_pool comes from
/// ScanOptions.
std::shared_ptr<parquet::ReaderProperties> reader_properties;
/// Arrow reader properties. Not all properties are respected: batch_size comes from
/// ScanOptions. Additionally, dictionary columns come from
/// ParquetFileFormat::ReaderOptions::dict_columns.
std::shared_ptr<parquet::ArrowReaderProperties> arrow_reader_properties;
};
```
