I am having a performance issue while I am using Bookmark (especially when I try running the report in PowerBI service).
This is related to my previous post.
I have four hierarchies of data that I am trying to present. The Fact table has little over a million row of data.
When it was three hierarchies, there was no issue with performance.
But, when it hits the fourth hierarchy and when I added a filter to visual, it is creating performance issue.
And then, when I clicked a Bookmark at PowerBI service for this visual (Matrix with four level of hierarchy with a a filter), visual crashes.
Bottom is screen shot of the error message:
I am trying to find a solution so that I could apply one more filter logic.
Here are my quetions:
1) Regards to using Bookmark, is there any difference of performance when Bookmark if it is used or not in PowerBI Service?
2) I am using Azure SQL on the backend (querying data from SQL View) pulling over 1 million rows of data. Should I consider using other database like Azure Databricks or some other storage? Actually, this is not something I could change as it is management decision 😞
3) Is it better to use one table with duplicate rows of data to aggregate data or use a separate dim table (for data like person's name & its ID)?
4) I tried Power Query to aggregate data. But, I ended up Grouping all columns we had before Grouping because I need to show all columns in order to leave the relationships with other tables that I had earlier. So, there is no point as all count is 1 (after trying Grouping all columns).
Is there any advice?
