My ETL team has created a View in oracle and I am using that to create Tableau extracts for my dashboard. This is working so fine until this . Recently they have used normalization in this view and that's when I see my dashboard performance became too slow.
ETL team has no issues in their View performance. But I am seeing a drastic low performance at my dashboard end.
Could any one provide me any workaround or suggestion on this to make my dashboard works faster.
