Supabase Storage now supports the S3 protocol, allowing developers to use it with thousands of tools that already support the protocol. This update also includes resumable uploads, which are now generally available, and multipart uploads via the S3 protocol. The S3 compatibility enables data scientists and engineers to use popular tools like DuckDB and ClickHouse directly with Supabase Storage. The company has also improved error codes, added cross-bucket transfers, and decoupled dependencies, making Storage a standalone service.
