Month: 2026-04 Focus: Bundle API Documentation and Developer Experience (DX) improvements for tigris-os-docs. Key features delivered: - Delivered comprehensive Bundle API documentation for streaming multiple objects as a tar archive in a single request (POST /{bucket}?bundle), including API reference, compression options, error handling modes, limits, and SDK examples for Python, Go, and JavaScript. - Developer experience enhancements: reorganized content to prioritize SDK examples, clarified error handling (BundleError/fail-mode) in Python examples, and introduced a context manager pattern for automatic connection cleanup. - BundleResponse metadata properties added and documented (object_count, bundle_bytes, skipped_count). - Documentation and examples updated for PyTorch usage; fixes included missing imports and ensuring s3_client is passed as a constructor parameter. - Cross-language SDK guidance updated to improve onboarding and usage flow across Python/Go/JS. Major bugs fixed: - No major bugs fixed this month; primary focus was on documentation quality and developer experience improvements. Minor fixes included updates to examples (e.g., PyTorch) and consistency improvements across docs. Overall impact and accomplishments: - Accelerated customer onboarding and reduced support time by delivering clear guidance and robust examples for the Bundle API, enabling efficient streaming of bundles. - Improved API discoverability and reliability through well-structured documentation and practical usage scenarios. - Demonstrated cross-language proficiency by aligning Python/Go/JS SDK examples with real-world usage patterns. Technologies/skills demonstrated: - API documentation, REST endpoints, tar streaming concept, error handling patterns (BundleError, fail-mode), context managers, cross-language SDK examples (Python, Go, JavaScript), and documentation tooling.
