Hello,
I created a Power BI report using BigQuery as the data source in import mode, and I published it on my company's Power BI Services. I find that the refresh time for the semantic model is very long.
In my case, I use a table with 30 million rows and 40 columns (no Power Query transformation steps), and it takes more than 5 hours to refresh the data, whether it's on Desktop or online.
I would like to hear your feedback and know how long it takes on your side to refresh data and how many rows you're working with, in order to know if there is an issue with PBI Services in my company.
Best Regards.
