Problems with Data Flow

Hi Syndicate_Admin ，

If you are a premium license, you can use the enhanced compute engine to increase the data stream refresh speed and thus avoid timeout errors.

The enhanced compute engine in Power BI enables Power BI Premium subscribers to use their capacity to optimize the use of dataflows. Using the enhanced compute engine provides the following advantages:

• Drastically reduces the refresh time required for long-running ETL steps over computed entities, such as performing joins, distinct, filters, and group by
• Performs DirectQuery queries over entities
