- Using fsspec Filesystems 14079
- DuckDB support for fsspec filesystems allows querying data in filesystems that DuckDB's httpfs extension does not support. fsspec has a large number of inbuilt filesystems , and there are also many external implementations . This capability

Firstly, you must install duckdb and fsspec , and a filesystem interface of your choice. pip install duckdb fsspec gcsfs Then, you can register whichever filesystem you'd like to query:...import duckdb from fsspec import filesystem # this line will throw an exception if the appropriate filesystem interface is not installed duckdb.register_filesystem(fi...lesystem('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.... - https://man.mtool.work/duckdb/2.0/guides/python/filesystems.html

- S3 API Support 8136
- The httpfs extension supports reading/writing/ globbing files on object storage servers using the S3 API. S3 offers a standard API to read and write to remote files (while regular http servers, predating S3, do not offer a common write API)
.... DuckDB conforms to the S3 API, that is now common among industry storage providers. Platforms The httpfs filesystem is tested with AWS S3 , Minio , Google Cloud and lakeFS . Other services that implement the S3 API (such as Cloudflare R2...-bucket⟩/⟨filename-2⟩.parquet' ]); Globbing File globbing is implemented using the ListObjectsV2 API call and allows using filesystem-like glob patterns to match multiple files, for example: SELECT * FROM read_parquet('s3://⟨your-bucket⟩/*.parquet'); This... - https://man.mtool.work/duckdb/2.0/core_extensions/httpfs/s3api.html
