Content Endorsement in Power BI

Published 2022-11-29 by Kevin Feasel

Soheil Bakhshi helps us find the best data:

One of the key aspects of users’ experience in Power BI is their ability to collaborate in creating and sharing content, making it an easy-to-use and convenient platform. But the convenience comes with a cost of having a lot of shared content in large organisations raising concerns about the content’s quality and trustworthiness. It would be hard, if not impossible, to identify the quality of the contents without a mechanism to identify the quality of the contents. Content endorsement is the answer to this.

“I’m Commander Shepherd and this is my favorite dataset on the Power BI Citadel.”

Partitioning Data in Power BI

Published 2022-11-28 by Kevin Feasel

Paul Turley continues a series on working with large amounts of data in Power BI:

You don’t have to have massive tables to benefit from partitioning. Even tables with a few hundred thousand records can benefit from partitioning, to improve data refresh performance and to detect source data changes. There is little maintenance overhead, so the benefits usually outweigh the cost, in terms of effort and management.

Testing Power BI REST APIs

Published 2022-11-23 by Kevin Feasel

Gilbert Quevauvilliers tries it:

Did you know that there is an easy way to run and extract Power BI REST API data?

The good news is that you can do this directly in your web browser. You don’t have to install or configure anything!

The method below works well if you want to either test the API to see what it returns.

Or if you want to run it to extract some data.

Read on for the process.

Reviewing an Existing Data Model with Power BI Model Documenter

Published 2022-11-23 by Kevin Feasel

Marc Lelijveld wants to see what’s out there in the wild:

In some scenarios, it can happen that you do not even have a Power BI desktop data model. For example, when you migrated from Analysis Services to Power BI Premium, or in case you have to deal with large datasets and it is directly developed using Visual Studio, Tabular Editor or any other tool of your preference and deployed over the XMLA endpoint. Similar setup could be that you once enriched your data model using Tabular Editor or ALM Toolkit, which resulted in the fact that your Power BI Desktop file, is no longer your golden version of your data model.

Another scenario could be gaining an overview of partitioning when using incremental refresh. The partitions of Incremental Refresh are only generated in the Power BI Service. So, including this information in your generated documentation is only possible when you connect directly to the Power BI Service.

But what if you still want to show a complete view of your Power BI data model, and extract insights using the Power BI Model Documenter? I can tell you; it is possible!

Read on to see what you can do in that case.

Essential Power Tools for Power BI Desktop

Published 2022-11-22 by Kevin Feasel

Jason Cockington makes several recommendations of external tools for Power BI Desktop:

The External Tools ribbon is a feature that has been available in Power BI Desktop since the July 2020 release.  This feature should be considered essential to anyone who is regularly working in the Power BI space.    In this article I recommend my top five External Tools, that I consider essential to any Power BI developer.

Read on for the recommendations. I regularly use two of the five but these do look good.

Fitting 10 Pounds of Data into a 5-Pound Power BI

Published 2022-11-22 by Kevin Feasel

Chris Webb does some compacting:

Power BI can handle large data volumes, but just how much data can you load into Power BI? Can Power BI handle big data? How big is “big” anyway? These are questions you may have when you’re starting out on a new Power BI project and the answers can be hard to find. Indeed the answer in most cases is “it depends”, which isn’t very helpful. In this post I will try to explain the various limits on Power BI dataset size and how you can know if you’re likely to hit them.

Data Scaling Thoughts for Power BI

Published 2022-11-21 by Kevin Feasel

Paul Turley starts a series:

The Power BI service can handle a lot of data, but just because your data sources are big doesn’t mean that your Power BI datasets will also take up a lot of space. If the data model is designed efficiently, even terabytes of source data will usually translate into megabytes, or a few gigabytes of dataset storage at most. As the industry has largely made the transition from on-prem SQL Server Analysis Services and AAS tabular models to Power BI datasets in Premium capacity, the size limits in the cloud service are notable. The following reference chart from the Microsoft Learning docs shows that a P1 Premium dedicated capacity is limited to 25 GB per dataset. That’s a lot but there are Premium capacity SKUs that can handle up to 400 GB of compressed data in an in-memory data model.

Defragmenting Power BI Fact Tables

Published 2022-11-16 by Kevin Feasel

Chris Webb reminds us that Power BI incremental refresh can lead to some fragmentation:

A lot of people are building large datasets in Power BI Premium nowadays, and if you’re building a large dataset you’re very likely to be using Power BI’s incremental refresh functionality with your fact tables or manually creating and refreshing partitions in them. If so, you should occasionally do a special kind of refresh to shrink the dictionaries on your fact tables.

Read on for a test of the most extreme scenario, though even less extreme versions can be bad.
