refreshing a huge number of rows in a table

hi guys,

the problem is i have a table that contains 20 million of records. every time i want to refresh the data i should wait about 30 to 45 minutes to complete. the question is that is there any way to update 5 last million records of a table? or any other solution to avoid waiting too much?

Thanks

alisoroush7 Yes, you can use Incremental Refresh. https://www.bing.com/ck/a?!&&p=1eb4908b95b30592JmltdHM9MTY3MTIzNTIwMCZpZ3VpZD0zMWJiZmJkOC1lYzJlLTY2NTAtMTc1MC1lOTg4ZWRiZDY3YzcmaW5zaWQ9NTE5MQ&ptn=3&hsh=3&fclid=31bbfbd8-ec2e-6650-1750-e988edbd67c7&psq=incremental+refresh+power+bi&u=a1aHR0cHM6Ly9sZWFybi5taWNyb3NvZnQuY29tL2VuLXVzL3Bvd2VyLWJpL2Nvbm5lY3QtZGF0YS9pbmNyZW1lbnRhbC1yZWZyZXNoLW92ZXJ2aWV3&ntb=1

Hi alisoroush7 ,

There are a few options you can consider to try and reduce the time it takes to refresh your data in Power BI:

Use DirectQuery mode: Instead of importing all of the data into Power BI, you can use DirectQuery mode to connect directly to the data source and query the data on demand. This can be faster, especially if you have a fast, efficient data source and a well-designed database. However, it may not always be possible to use DirectQuery mode, depending on the data source and the requirements of your report.
Optimize the data source: If you are using an on-premises data source, there are several ways you can try to optimize the data source to improve performance. For example, you can try indexing the tables in the data source, or partitioning the data to spread it across multiple tables or servers.
Use incremental refresh: If your data source supports it, you can use incremental refresh to only refresh the data that has changed since the last refresh. This can be a significant time saver, especially if you have a large dataset that changes frequently.
Use a faster computer: If you are using a slower computer or one with limited resources (e.g. CPU, RAM), this can contribute to the slow refresh times. Upgrading to a faster computer with more resources may help.
Use a faster connection: If you are using a slow internet connection, this can also contribute to slow refresh times. Using a faster connection (e.g. a wired Ethernet connection instead of WiFi) may help.

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry
