May 1, 2025May 2025 monthly summary for sogis/gretljobs: Delivered four targeted items that improve data quality, ingestion reliability, and testing coverage, translating into faster, more accurate data availability for downstream systems and stakeholders. Key features include updating agi_av_meldewesen to identify using building name, including EGID in outputs, and updating the README for clarity; migrating denkmalschutz inserts to the versioned ada_denkmalschutz_pub_v1 schema to ensure correct data insertion; enabling MGDM data version 1.5 with updated upload task to publish the latest data and making publish depend on the updated upload task; establishing an SFTP upload test infrastructure via arp_sein_upload_test module and corresponding test configuration to validate end-to-end uploads. This work demonstrates strong SQL/versioned schema handling, data pipeline orchestration, and test automation.
