Monthly performance summary for 2025-10: Delivered targeted feature and documentation enhancements across proton and docs repositories, reinforcing data ingestion reliability and developer usability. Key feature: PostgreSQL external tables now support an on_conflict option to define conflict resolution strategies during data insertion, with storage layer updated to honor this setting. Documentation: External Tables docs for MySQL and PostgreSQL updated with clarified use cases, syntax explanations, and practical config examples (config_file, named_collection). These changes improve data integrity, reduce operational risk during bulk loads, and accelerate onboarding for new users. No major bugs fixed this month; stability and maintainability improvements were prioritized.
