- Add BedrockFilesHandler with S3 upload functionality using SigV4 authentication - Integrate into litellm.create_file() API with custom_llm_provider='bedrock' - Support all standard AWS authentication methods (env vars, profiles, IAM roles) - Require LITELLM_BEDROCK_BATCH_BUCKET environment variable - Return OpenAI-compatible OpenAIFileObject responses - Follow existing patterns from Azure/Vertex AI file implementations Enables file upload for Bedrock batch inference workflow. Part 1/3 of Bedrock batch processing implementation.
- Add test_bedrock_files_handler.py with tests for BedrockFilesHandler functionality - Tests cover file creation, upload, and management operations - Located in tests/test_litellm/llms/bedrock/files/ following standard structure
- Remove failing integration test that had cross-branch dependencies - Keep focused unit tests that properly test BedrockFilesHandler functionality - Integration test will be restored when all branches are merged
- Format bedrock files handler according to project style guidelines - Keep consistent with LiteLLM codebase formatting standards
- Create BaseBatchesConfig base class for batch operations - Add create_batch and async_create_batch methods to llm_http_handler - Fix type handling in bedrock files handler for FileTypes union - Support provider-specific batch transformations following files pattern - Add proper imports for CreateBatchRequest and Batch types - Enable batch creation through unified HTTP handler interface
- Add Bedrock-specific logic to create_batch and async_create_batch methods - Add Bedrock-specific logic to create_file and async_create_file methods - Implement _create_bedrock_batch and _async_create_bedrock_batch for AWS Bedrock Model Invocation Jobs - Implement _create_bedrock_file and _async_create_bedrock_file for S3 file uploads - Route all Bedrock operations through unified llm_http_handler instead of separate handlers - Support full AWS integration with SigV4 signing and credential management - Return OpenAI-compatible responses with Bedrock metadata for tracking
…handler - Remove BedrockFilesHandler import and instance from files/main.py - Replace bedrock-specific file creation with unified llm_http_handler approach - Create inline BedrockFilesConfig class for provider configuration - Remove old litellm/llms/bedrock/files/ directory and handler implementation - Remove obsolete test files for standalone handler - Maintain all AWS parameter passing and functionality through new architecture
- Add comprehensive integration tests for Bedrock batch functionality - Tests cover end-to-end file upload and batch creation workflow - Located in tests/test_litellm/llms/bedrock/integration/ - Tests integration with unified llm_http_handler implementation - Consolidates testing from separate PR into main implementation PR
- Fix LlmProviders import issue in files/main.py by removing duplicate import - Refactor create_file function by extracting Bedrock handling into helper functions - Add utility functions to bedrock/common_utils.py for file and batch operations - Refactor _async_create_bedrock_file in llm_http_handler.py using utility functions - Extract file content processing, S3 key generation, and upload preparation logic - Reduce function complexity and improve code reusability across Bedrock operations Resolves PLR0915 (too many statements) and F823 (local variable referenced before assignment) linting errors
