Neue Views in Data Shares zur Vereinfachung von Usage Group-Abfragen

Bisher war beim Schreiben einer Abfrage gegen unsere Data Shares mit Usage Groups die vollständige Usage Group-Definition in der Abfrage enthalten, was zu erhöhter Abfragekomplexität und schlechterer Lesbarkeit führte.

Wir haben seitdem neue Views erstellt, die die Usage Group-Definition abstrahieren und so zu einfacheren Abfragen führen.

1select start_day as day, sum(sum_query_cost) as sum_query_cost from select_datashare.transformed.daily_workloads_usage_groups where usage_group in ('Marketing Team') and start_day >= '2024-09-01' and start_day <= '2024-09-14' group by all order by day desc nulls last
