At @Wix, we cut monthly cloud data 📊 costs by 50% (!) - while running 100K+ tables across 2 Iceberg catalogs and trillions of CPU milliseconds in Trino & Spark.
Here’s how we did it (without slowing teams down!):
⚙️ Job-level telemetry & ownership across Trino, Spark, and Airflow (100% coverage via Platyspark)
💰 Simple cost models (e.g. $0.000002 per Trino CPU ms) and efficiency KPIs like “cost per 1B clickstream events”
📊 Dashboards that drive accountability, surfacing daily usage for every team
🙌 Engaged data teams - quick wins (95% storage savings by reducing job frequency) - deeper refactors
