Hi Team,
We have 13 Dimension tables and 1 fact table. I've designed the fact job in the both the ways(by joining all the Dimension table and fetch SK values and by lookup all the dimension table and fetch SK values) but both are taking so much of time to load (for 36million records its took around 7 hours to complete) pls provide me some tips to improve the performance of fact load..The logic which am using is simple upsert logic
