Power Bi Service - Slow load from BigQuery

Hi, I have large(50M+ Rows) data model storage on a BigQuery model. I've created a view to develop my Model in PowerBI Desktop and it worked fine and even importing all the rows to my Power BI desktop file, it tooked a while but worked. I Published my model to PowerBI Service, but the refresh data it's taking too long and only on PowerBI's side. The query ran suceffully on Google Biguery in just 45 seconds and now, more then one hour later the PowerBI still updating the dataset. Is there a way to improve de connection between Google and Microsoft?

 

Time spent on BigQuery:

Hi @FelipeDBA , why is the transfer speed so low? transferring 20Gbs in an hour is so low 😞 @otravers  we have this kind of use case as well where we cannot perform incremental refresh since historical data is changing every day.

Hi @FelipeDBA ,

 

You can use Incremental refresh and real-time data for datasets. With the help of it, Datasets with potentially billions of rows can grow without the need to fully refresh the entire dataset with each refresh operation.

Besides, you can manage the storage mode. The storage mode lets you control whether Power BI Desktop caches table data in-memory for reports. With the help of it, tables that aren't cached don't consume memory for caching purposes. You can enable interactive analysis over large datasets that are too large or expensive to completely cache into memory. You can choose which tables are worth caching, and which aren't.

 

For more details, please refer to:

@otravers It is on a Premium Workspace.

Did the refresh eventually complete? I'd look at incremental refresh to avoid reloading 50M+ rows each time, assuming most of these rows are now historical records.

Why dont focus on solving the real Issue? Which is the transfer speed

Is the dataset in a Pro or Premium workspace?
