Duplicate Requests Issue in Power BI Custom Connector Development
The important question here is this: do you get duplicate requests in both the Power BI Service and in Power BI Desktop, or only in Desktop? If it's the latter then it's less of a problem because the Power BI Service is where good performance really matters.
The issue occurs in Power BI Desktop, but it is still significant for our customers because they use Desktop to build reports before publishing them to the Power BI Service. In Desktop, re-requesting large datasets causes performance issues, slowing down the process and leading to frustration for customers. Additionally, generating this data involves running SQL queries in Azure, which incurs unnecessary costs when duplicate requests are made. Although performance in the Power BI Service is critical, addressing this issue in Desktop is also important for improving customer satisfaction and reducing operational costs.
