We have built a process visualizing data on Tableau. The data is retrieved from SAP Hana and it was a business requirement that the type of connection was Live. As the granularity of the data we are visualizing is quite low (around 5 millions rows on the fact table), there are charts that take up to 30-35 seconds to load. Is there any way of lowering that performance scenario? Is there any Tableau tool to help improving performance in this situation? Any ideas?
