What are the risks of using DirectQuery in Power BI?

[rhutvik14]

When developing Power BI solutions, the challenge is to harness the power of DirectQuery while remaining aware of the risks involved. First, using DirectQuery gives you real-time access to the data, which can sometimes lead to latency or slow loading times. Every interaction with a report results in a fluid query being sent to the source database. A single query can take a long time if it contains a lot of classes, complex model relationships, or if it references a fact table with huge amounts of data.

The next risk is that there may be limited functionality in some of the features of Power BI. Consider Quick Insights, for example, some of the DAX functions may work differently in DirectQuery than in Import mode. This has the potential to lead to a missed part of your analysis, or to the wrong report. Understanding how to configure your environment so that you do not run into serious barriers will often be a key component of a Power BI Course in Pune, and hands-on training will prepare users for making these trade-offs in a real-world project.

Security is also a risk. Since DirectQuery is a live connection, the data is not being stored in Power BI, but rather being frequently queried. Therefore, every user interaction depends on securely and continuously accessing the database. Power BI Training in Pune typically includes best practice training around configuring gateway connections and row-level security, along with hands-on training.

Lastly, Power BI Classes in Pune frequently refer to the performance tuning of queries and the performance tuning data sources as critical to ensuring portals and dashboards are responsive and efficient when reconnecting using DirectQuery.
