Example
The following is an example of using `fsspec` to query a file in Google Cloud Storage (instead of using their S3-compatible API).  
Firstly, you must install `duckdb` and `fsspec`, and a filesystem interface of your choice.  
```bash
pip install duckdb fsspec gcsfs
```  
Then, you can register whichever filesystem you'd like to query:  
```python
import duckdb
from fsspec import filesystem

# this line will throw an exception if the appropriate filesystem interface is not installed
duckdb.register_filesystem(filesystem('gcs'))

duckdb.sql("SELECT * FROM read_csv('gcs:///bucket/file.csv')")
```  
> These filesystems are not implemented in C++, hence, their performance may not be comparable to the ones provided by the `httpfs` extension.
> It is also worth noting that as they are third-party libraries, they may contain bugs that are beyond our control.
