If your data source is online such as in onedrive or sharepoint online, they useautomatic refresh. This means no user configuration is necessary in order for the dataset to be refreshed on a regular basis. Data refresh settings are configured for you by Power BI. For online service providers, refresh usually occurs once-a-day. For files loaded from OneDrive, automatic refresh occurs about every hour for data that does not come from an external data source. While you can configure different schedule refresh settings and manually refresh, you probably don’t need to.
Unfortunatelly it does not refreshed automaticly. I even do not want this to be refreshed automaticaly.
Every month my client puts csv file on his ondrive/sharepoint which I have to recconect to power bi dashboard.
This file is now about 1.1mln rows and weights above 1GB. It takes more then hour to refresh (if I do not get time out error).
My assumption is the connector to sharepoint folder is very very inefficient. Refreshing the same file from my local computer is not a problem. It running quite fast. So it is not a dataset size issue. Do not tell me please to amend architecture to store data in a different place like database or azure storage. I know this, but at this moment we use Onedrive/Sharepoint as a data storage.
It is quite common practice but I do not understad why it is not so efficient? Both are Microsofts ones, ya?
I find quite a few discussions here on forum, people brought similar questions. Many of them with no sollution given.
I am using the November 2018 version of desktop and experiencing refresh timeouts trying to load a csv file from SharePoint Online. The file has 17,000+ records and is 45Mb in size. I noted that this is bigger than the 30Mb that will open in Excel on-line. I opened the file and saved as an xlsx file in the same SharePoint folder. It now only takes a few seconds to refresh. The file size now though is only 2.25Mb in size. So it seems I can either wait for the organisation to update the desktop version, or change the csv files to xlsx.
I'm experiencing the exact same issue: it's taking a very long time to load a 1.5 million rows csv file. I can't convert it to xls because it's too large. How is your file performance with the latest pbi update (Apr 19)?
