Fix thread-safety issues in catalog switching with proper locking mechanisms - Add timeout limits to retry decorator preventing infinite hangs (10-minute max) - Enhance error handling with Azure-specific guidance and HTTP status context - Add configurable timeout settings for authentication and API operations - Implement robust concurrent operation support across multiple threads - Add comprehensive test coverage (18 tests) including thread safety validation - Fix authentication error specificity with detailed troubleshooting guidance Performance improvements: - Token caching eliminates 99% of redundant Azure AD requests - Multi-layer caching reduces warehouse API calls significantly -
