Sep 1, 2025September 2025 monthly summary for OWOX/owox-data-marts focused on reliability, usage visibility, and scalable data-marts operations. Delivered consumption tracking via Pub/Sub with cross-application integration (Google Sheets, Looker Studio report writers, and the connector execution service) to log resource usage and enable better capacity planning and cost control. Resolved critical stability issues: cascading deletes for report_data_cache to fix report deletion crashes, with an accompanying migration to manage the schema change. Improved time-based triggers reliability by correcting concurrency and MySQL trigger versioning, ensuring only a single processor runs and versions update correctly. Technologies demonstrated include Pub/Sub messaging, MySQL triggers and migrations, and telemetry across reporting and data-mart components, delivering enhanced stability, visibility, and scalability for data-marts operations.
