Setting up Azure Purview for Power BI

Published 2020-12-10 by Kevin Feasel

Soheil Bakhshi has a great step-by-step walkthrough for setting up Azure Purview:

Microsoft newly announced a piece of very exciting news that Azure Purview now supports Power BI. This is massive news from a data governance point of view. Azure Purview is the next generation of Azure Data Catalog with more metadata discovery power and the ability to use sensitivity labels. After reading the news, I immediately decided to set up my test environment and give it a go. I followed the steps mentioned in this article on the Microsoft documentation website but I faced some difficulties to get it to work. And here we are, another blog post to help you to set up the Azure Purview for Power BI.

All About Dot Plots

Published 2020-12-10 by Kevin Feasel

Cole Nussbaumer Knaflic talks about one of my favorite plot types:

The term “dot plot” can be used for any graph that is encoding data in a dot or small circle. There are a few common types that I’ll focus on here. If you’ve ever asked yourself—What is a dot plot? How do I interpret a dot plot? When should I use a dot plot? or What are pros and cons of dot plots?—you’ll find the answers in this post. I’ll also share some tips on creating them and where to find examples that will inform and inspire.

A Primer on Locking and Deadlocks

Published 2020-12-10 by Kevin Feasel

John McCormack explains locks and deadlocks:

Blocking is the real world impact of locks being taken on resources and other lock types being requested which are incompatible with the existing lock. You need to have locks in order to have blocking. In the scenario where a row is being updated, the lock type of IX or X means that a simultaneous read operation will be blocked until the data modification lock has been released. Similarly, data being read blocks data from being modified. Again, there are exceptions to these based on the isolation level used.

Blocking then is a perfectly natural occurrence within SQL Server. In fact, it is vital to maintain ACID transactions. On a well optimised system, it can be hard to notice and doesn’t cause problems.

All things in moderation, even blocking.

Creating Property Names in Powershell

Published 2020-12-10 by Kevin Feasel

Jeffrey Hicks shares some Powershell API design tips:

When you build a PowerShell tool, you want the output to be easy to use. To me, this means having clearly defined property names. Dave has a command in the module to get a Twitter user account. Here’s what it currently writes to the pipeline.

For the sake of demonstration, assume that the Get-TwitterUser command is your code that is invoking a REST API and returning a custom object to the pipeline.

The property names are mostly clear, although not very PowerShell friendly. How many native PowerShell commands do you run that have properties that look like this? Let’s fix this.

Read on to see those properties and how you can make them more Powershell-friendly.

Troubleshooting an Error: Insufficient System Memory

Published 2020-12-10 by Kevin Feasel

Lee Markup walks us through an issue:

In my own local SQL Server I ran across a problem starting the SQL instance. I went to SQL Server configuration Manager and manually started the SQL Server instance. The UI showed the instance had started. I opened SSMS and tried to connect. And I waited, waited and waited some more until it didn’t connect and threw an error.

Read on to see how Lee was able to find and correct the issue without actually being able to start up SQL Server.
