Introduction

Are you looking to optimize your Power BI reports? Do you want to capture fast-moving data and ensure real-time updates? If so, then you need to understand the power of incremental refresh with direct query in Power BI.

Incremental refresh is a feature in Power BI that allows you to load and refresh only the changes made to your data, rather than reloading the entire dataset. This can significantly improve the performance of your reports and reduce the time required for data refreshes.

In this article, we will explore the benefits of incremental refresh with direct query in Power BI, as well as how to configure and use this feature effectively.

Benefits of Incremental Refresh with Direct Query

There are several benefits to using incremental refresh with direct query in Power BI:

Improved performance: By only loading and refreshing the changes made to your data, incremental refresh can significantly improve the performance of your reports. This is especially beneficial for large datasets or datasets that are frequently updated.
Real-time updates: With incremental refresh, you can capture fast-moving data and ensure that your reports are always up to date. This is crucial for organizations that require real-time insights and need to make data-driven decisions on the fly.
Reduced data storage: By only loading and refreshing the changes, incremental refresh can help reduce the amount of data storage required for your reports. This can result in cost savings, especially for organizations that have large datasets.
Flexible data refresh schedules: With incremental refresh, you have the flexibility to choose when and how often you want to refresh your data. This allows you to align your data refresh schedules with your business needs and ensures that you have the most up-to-date information for your reports.

Configuring Incremental Refresh with Direct Query

To configure incremental refresh with direct query in Power BI, follow these steps:

Ensure that you have Power BI Premium or Power BI Embedded capacity, as incremental refresh is only available with these licensing options.
Create a dataset with direct query mode enabled.
Go to the dataset settings in the Power BI service and navigate to the 'Incremental Refresh' tab.
Enable incremental refresh for the dataset by toggling the switch.
Define the columns that will be used to determine the changes in your data. This can be done by specifying a date or time column, or by using a numeric column with a timestamp.
Configure the refresh policy for your dataset. This includes defining the minimum and maximum values for your date or time column, as well as specifying the refresh window and retention period for your data.
Save and publish your dataset.
Test the incremental refresh by making changes to your data and verifying that only the changes are loaded and refreshed in your reports.

Best Practices for Using Incremental Refresh with Direct Query

Here are some best practices to keep in mind when using incremental refresh with direct query in Power BI:

Choose the right columns: When defining the columns for incremental refresh, choose columns that are frequently updated and have a high impact on your reports. This will ensure that only the relevant data is refreshed, improving the overall performance.
Set appropriate refresh windows: Define the refresh window for your dataset based on the frequency of data updates. For example, if your data is updated hourly, set a refresh window of one hour to capture all the changes within that timeframe.
Monitor the refresh performance: Regularly monitor the performance of your incremental refresh to ensure that it is working effectively. If you notice any issues, such as slow refresh times or data discrepancies, make the necessary adjustments to your configuration.
Consider data retention: Determine the retention period for your data based on your reporting needs. For example, if you only need to analyze data from the past six months, set a retention period of six months to reduce the amount of data storage required.

Conclusion

Incremental refresh with direct query is a powerful feature in Power BI that can help you optimize your reports, capture fast-moving data, and ensure real-time updates. By following best practices and configuring incremental refresh effectively, you can significantly improve the performance of your reports and reduce the time required for data refreshes.
