Jan 1, 2025January 2025 highlights for incubateur-ademe/quefairedemesobjets: a focused sprint that improved data quality, expanded data coverage, and strengthened deployment reliability while enhancing automation and governance. Key outcomes include a data normalization configuration refactor and Source object codes standardization to reduce ingestion errors and simplify onboarding of new sources; expansion of data sources with ECOPAE and Cyclevia; robust workflow improvements including online deduplication tasks and rename operations, plus model code validation to strengthen data integrity. Operationally, the Airflow cluster was deployed on Clever Cloud and the data application integrated into the Docker Airflow Scheduler, with fixes to DAG synchronization and Airflow log storage over S3 to improve reliability and scalability. Administrative tooling and documentation were enhanced through Makefile improvements (run-all and db-restore targets, and a fix to db-restore), a documented rollback process, and a UI enhancement to duplicate an actor from its revision, together reducing manual effort and risk.
