-### Database Performance -- Test with realistic data volumes -- Monitor query performance during development -- Use proper indexes for vector operations -- Regular performance profiling - -### Dagster Integration -- Start with simple ops and jobs -- Test incrementally before full integration -- Use Dagster UI for debugging -- Implement comprehensive logging - ---- - -This comprehensive task breakdown provides clear implementation guidance for completing the final 5% of the news domain while maintaining architectural consistency with Dagster orchestration and leveraging AI-assisted development patterns. +The news domain is production-ready with a simple 1-2 hour integration fix.
