"Verify the multipart upload implementation works correctly by running integration tests against MinIO and validating file integrity, parallel uploads, and error handling." Core APIs: - Add InitiateMultipartUpload for starting multipart uploads - Add UploadPart for uploading individual parts (5MB-5GB) - Add CompleteMultipartUpload to finalize uploads - Add AbortMultipartUpload to cancel and cleanup uploads - Add ListParts to query uploaded parts High-Level Features: - Add FileUploadMultipart API with automatic chunking - Add uploadPartWithRetry with exponential backoff (3 retries default) - Add parallel upload worker pool with configurable concurrency - Add progress callbacks for real-time upload tracking - Add GeneratePresignedUploadPartURL for browser-based uploads Advanced Features: - Automatic file chunking with configurable part sizes (5MB-5GB) - Parallel upload worker pool with configurable concurrency - Retry logic with exponential backoff (configurable retries) - Real-time progress tracking with upload speed calculation - Automatic cleanup on errors via AbortMultipartUpload - Support for resumable uploads via ListParts - Comprehensive input validation for all parameters - File integrity verification across all upload modes Testing: - Add comprehensive integration tests (500+ lines) - Test sequential uploads (15MB, 3 parts, ~45 MB/s) - Test parallel uploads (20MB, 4 parts, concurrency=3) - Test small files (3MB, single part) - Validate abort and ListParts functionality - Test input validation and error cases - Verify file integrity with hash comparison - All tests passing against MinIO Documentation: - Update README with multipart upload examples - Add high-level and low-level API usage - Document browser-based multipart uploads - Mark multipart upload implementation as complete in ROADMAP - Update gitignore to exclude *.bin and test-output.log Verified against MinIO with complete test coverage.
