Schedule Refresh Issue

[ShadabKhan9970]

One of my dataset is taking to much of time for refresh before it is taking 10 mins for refresh. The dataset size is also 14 mb. I have set multiple time for refresh for that dataset.

If your dataset is taking too long to refresh, there are several potential causes and steps you can take to address the issue:

1. Check Data Source Performance:

   • Ensure that the data source itself is performing well. Slow performance on the source system can impact the refresh time.

2. Optimize Query Performance:

   • Review the queries in your Power Query Editor in Power BI Desktop. Look for any complex or inefficient transformations that could be optimized. For example, removing unnecessary columns or reducing the number of rows loaded can significantly improve refresh times.

3. Check for Gateway Issues:

   • If you are using a gateway for an on-premises data source, ensure that the gateway is properly configured, up-to-date, and running.

4. Incremental Refresh:

   • Consider using incremental refresh if your data source supports it. This allows you to refresh only the new or modified data, reducing the amount of data that needs to be processed.

5. Optimize Data Model:

   • Ensure that your data model is optimized. Avoid creating unnecessary relationships, remove unused tables or columns, and optimize data types.

6. Check for Resource Contention:

   • If you're using shared resources (like Power BI Pro), check if there are other heavy workloads running at the same time that might be affecting performance.

7. Schedule Refresh During Off-Peak Hours:

   • If possible, schedule your dataset refresh during off-peak hours when there is lower demand on resources.

8. Use Dataflows (if applicable):

   • If your data is stored in a supported dataflow storage, consider using dataflows. Dataflows allow you to perform data transformation and preparation outside of your dataset, which can lead to faster refresh times.

9. Review Refresh History for Errors:

   • Check the refresh history to see if there are any specific errors or issues reported during the refresh process.

10. Monitor Memory Usage:

    • Ensure that your system has enough available memory during the refresh process. If resources are constrained, it can slow down the refresh.
