Jun 1, 2025June 2025 monthly summary for sfbrigade/datasci-earthquake: Delivered key workflow improvements, data handling optimizations, and reliability enhancements that strengthen ETL deployment, data parity across environments, and overall pipeline resilience. Implemented CI/CD workflow enhancements to detect ETL changes and conditionally push updates to develop and main branches, ensuring data parity across environments. Tuned liquefaction data processing with a tolerance of 0.0 to disable point collapsing for multipolygons and aligned related workflow/config changes. Strengthened test reliability by refactoring tests to use HTTP request mocks and simulating multiple consecutive 504 errors to ensure retry logic exhausts all attempts. These efforts reduce deployment risk, improve data consistency, and increase confidence in the ETL pipeline stability across production and development environments.
