While connecting Power BI to Azure Synapse offers numerous advantages, there are some limitations to consider. One limitation is related to the data refresh frequency and capacity. If you are working with a considerable volume of data, this can impact the performance of your reports, particularly during scheduled refreshes. Users need to optimize their queries and dataset sizes to improve efficiency.

Additionally, certain features in Power BI, like DirectQuery, may have restrictions when working with Azure Synapse. For instance, not all DAX functions are supported, which could lead to complications when trying to create complex calculations. Understanding these limitations will help users navigate the integration process more effectively and set appropriate expectations for their analytics initiatives.

Is it possible to visualize real-time data from Azure Synapse in Power BI?

Yes, it is possible to visualize real-time data from Azure Synapse in Power BI using the DirectQuery mode. This feature enables you to create reports that query data directly from the Azure Synapse environment without importing it into Power BI. Such an approach is highly beneficial for scenarios requiring up-to-the-minute data analysis, allowing organizations to act quickly based on current insights.

However, careful consideration should be taken regarding the performance implications of using DirectQuery. Since the queries are executed live against the data source, they can incur longer load times if not optimized properly. Ensuring that the underlying data model in Azure Synapse is well-structured and indexed will help mitigate performance issues, thus enhancing the real-time analytics experience in Power BI.
