How to refresh cloud data sources in Power BI using the gateway?
If you enable the checkbox Allow user's cloud data sources to refresh through this gateway cluster in the gateway configuration, as in the screenshot above, Power BI can use the configuration that the user defined for the cloud source under Data source credentials in the dataset settings. This can help to lower the gateway configuration overhead.
How can I increase the performance of my Power BI premium instance?

You’ve made the most awesome dashboard you can think of: Your users love it, the data is just right, and the feedback is amazing. There is only one problem - the data takes 1.5 hours to refresh from the database - and you need to refresh the data every 4 hours.
The "TEXT" Problem
My PBI refreshes used to take 45 minutes, and now takes 5 minutes. How did I accomplish this wonder? One of my colleagues pointed out I should be using "CAST" when querying the database.
Solution Execution
Luckily it’s rather easy to modify an existing PBIx file and using the below short cut will enable you to get started
FINAL WORD
To repeat: If working with very large databases using "CAST" can save you hours of pain and time outs and refresh issues.
ADVANCED USERS
The below is for advanced users who know ho wo to use PBI advanced query editor - this is the code generated by PBI. Note the double “" "” are needed for column names.

How does Power Bi refresh?
Power BI maintains a cache for every tile visual on your dashboards and proactively updates the tile caches when data changes. In other words, tile refresh happens automatically following a data refresh. This is true for both, scheduled and on-demand refresh operations. You can also force a tile refresh by selecting More options (...) in the upper right of a dashboard and selecting Refresh dashboard tiles.
What is Power Bi?
Power BI enables you to go from data to insight to action quickly, yet you must make sure the data in your Power BI reports and dashboards is recent. Knowing how to refresh the data is often critical in delivering accurate results.
Why is it important to check refresh history?
Checking the refresh history of your datasets regularly is one of the most important best practices you can adopt to ensure that your reports and dashboards use current data. If you discover issues, address them promptly and follow up with data source owners and gateway administrators if necessary.
What does the refresh history icon mean?
As the name implies, the refresh history enables you to review the success or failure status of past synchronization cycles. For example, a gateway administrator might have updated an expired set of database credentials. As you can see in the following screenshot, the refresh history shows when an affected refresh started working again.
How does automatic page refresh work?
Automatic page refresh works at a report page level, and allows report authors to set a refresh interval for visuals in a page that is only active when the page is being consumed. Automatic page refresh is only available for DirectQuery data sources. The minimum refresh interval depends on which type of workspace the report is published in, and the capacity admin settings for Premium workspaces and embedded workspaces.
What is Power Bi Dataset?
A Power BI dataset can operate in one of the following modes to access data from a variety of data sources. For more information, see Storage mode in Power BI Desktop.
Does Power Bi have a live connect?
Although DirectQuery mode and LiveConnect mode are similar in that Power BI forwards the queries to the source, it is important to note that Power BI does not have to transform queries in LiveConnect mode. The queries go directly to the Analysis Services instance hosting the database without consuming resources on shared capacity or a Premium capacity.
Why is my refresh time higher?
If you see high processor time, you likely have expensive transformations that aren't being folded, either because of the number of applied steps you have, or the type of transformations you're making, each of which can result in higher refresh times.
Why are refreshes more reliable?
Refreshes are more reliable - it's no longer necessary to maintain long-running connections to volatile source systems. Resource consumption is reduced - less data to refresh reduces overall consumption of memory and other resources.
What to do when you are experiencing timeouts?
If you are experiencing timeouts, consider optimizing your dataflow queries, and consider using query folding on your source systems.
Why is incremental refresh important?
It's important that the partition filters are pushed to the source system when queries are submitted for refresh operations . To push filtering down means the data source should support query folding, or you can express business logic through a function or other means that can help Power Query eliminate and filter files or folders. Most data sources that support SQL queries support query folding, and some OData feeds can also support filtering.
What is refresh statistics?
The refresh statistics provide valuable information you can use to optimize and speed up performance of your dataflows. In the following sections, we describe some scenarios, what to watch out for, and how to optimize based on the information provided.
How many options are there for optimizing high processor time?
There are two options for optimizing high processor time.
Can you download refresh history after dataflow refresh?
To understand run times, performance, and whether you're getting the most out of your dataflow, you can download the refresh history after a dataflow has been refreshed.
What is the fastest way to crawl a dashboard?
A big table can make the fastest dashboard crawl. Every time you use a slicer, the table will have to generate and display all the data in the dataset. For this reason, Microsoft added the convenient “top-n rows” feature. When activated, instead of showing the whole dataset, the table will limit itself to N rows.
Is Power Bi marketplace good?
The Power BI marketplace is a great resource for finding amazing widgets to present your insights. Even though sometimes you have no choice but to use them, I would advise you to stick to default widgets if you have the choice. If that fancy third-party widget looks slightly better, but slows down your dashboard, you should ask yourself the question if its worth implementing it. I’m not saying all marketplace widgets are slow, but some of the biggest speed improvements I made were by switching back to default slicers.
How to get data into PBI?
The only way to get data into PBI is through power Query. PBI has power query and power pivot as modelling tools. Unlike excel version, you cannot bring data directly in Power Pivot, so you have a query from a website. (google sheets in your case). If the refresh time is slow, then the query is slow.
Can Power Query be folded?
Power Query can push processing back to external databases like SQL etc., which is called query folding. However, as your data is in Excel it won't fold the queries anywhere. In other words, Excel is doing all the work as query folding to an external database isn't available.
Does PQ refresh all queries?
I've looked online and one site said that PQ updates ALL the queries when you do a refresh, so the more queries, the longer it takes. Another site said to enable the Fast Data Load under Query Options. I've done that, but it doesn't seem to help much.
