Sep 1, 2025September 2025: Blobscan/blobscan delivered reliability, security, and performance improvements with a focus on business value. Key features delivered include Blob Storage and Propagation Robustness (blob reconciliation, orphan blob scanning, propagation job recreation) plus a storage overhaul moving to a primary blob storage model. Admin API Authentication added API key-based admin access with updated context/utilities and tests. API Performance Improvements introduced caching for daily statistics responses and refactored Redis client setup to a singleton for improved latency and stability. REST API Startup Robustness now catches and logs initialization errors to prevent unhandled startup failures. API Indexing Robustness ensures an error is raised if a blob propagator is missing during indexing, preventing runtime failures. Overall impact: these changes reduce runtime risk, reduce latency for frequent read paths, and strengthen security and maintainability. They lay a foundation for scalable data access and faster navigation through data blocks and stats. Technologies/skills demonstrated include distributed storage architecture (blob propagation, primary storage redesign), API security (API keys), caching and Redis singleton patterns, database query optimization (LEFT JOIN), error handling and robustness, and test suite organization.
