Can`t load data to Power BI desktop
Hi all,
So my refresh is standing still for half an hour although it has finished load all rows to the data set
i`m using power bi desktop and my data from MySQL
Anyone know what kind of error is this?
thanks
Hi Haidann,
It seems like your query tables have invoked a large data table for many times.
Perhaps you can create a static query table to store it and reference the table in other queries instead of initialization the source table multiple times in different tables.In addition, you can also turn off 'include in refresh' option to cancel the large dataset refresh to improve the loading performance. (you can turn on the refresh of these large dataset in free time instead of keeping these refresh triggered every time you save back to data model)
BTW, I also list some links of performance tricks, you can take a look on them if they help for your scenario:Watch Your Steps! Power Query Performance Caution for Power BI

Hi Haidann,
Any advanced operation in your query tables? (e.g. merge, combine, reference other queries, invoke custom functions...)
If this is a case, you can refer to following link to add buffer functions to package these operations to reduce the duplicate memory spend on these looping calculations.How and When to use List & Table Buffer?

Dear Anonymous
Actually, my dataset has all of operations you have listed =)))
That could be the part of reason why my dataset keep failing to reload
I`ll try your suggesttion and keep you update asap
Many thanks
