[GitHub] [arrow] mapleFU commented on issue #33683: [C++][Parquet] Would Arrow::FileReader support filter evaluating and optimize by BloomFilter

   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;
   };
   ```
