14. How do you want to refresh data?
6/10/2018 8:03 AM
How do you want to refresh data?
Import (cached mode)
DirectQuery or Live connection
Refresh frequency
Scheduled – hourly (8x a day)
Premium allows for 48x a day
Real-time
Performance
No noticeable delay since data is already cached
Depends on how fast the data source is as queries are executed in real-time
Data storage in Power BI
Since it is cached mode, data is stored in the cloud
No data is stored in Power BI. Data is always on-premises*
Data size
Current limit of 1GB (compressed) per model
The on-premises database is the limit; no Power BI limitation
Security
Can create row-level security on the Power BI dataset (Import and DirectQuery)
Re-use on-prem role based row level security for Analysis Services. Non-SSAS supports Cloud RLS.
Data sources
All on-prem data sources supported can be used in import mode
Select data sources
*Some data is cached for optimizing first-time load performance
