Initial Thoughts on the Microsoft Fabric Data Science Experience

Tori Tompkins shares some thoughts:

Fabric is Microsoft’s recently announced SaaS all-in-one analytics platform. It brings together Azure Data Factory, Azure Synapse Analytics and Power BI into a single cohesive platform without the overhead of setting up resources, maintenance, and configuration. Fabric wouldn’t be an end-to-end data analytics platform without data science, so in this blog we will explore the data science and machine learning capabilities of Microsoft Fabric and assess where the platform fits in the completive data science landscape.

Click through for Tori’s overview, where Fabric does a good job in its preview, and where it currently falls short.

Error Trapping with Extended Events

Chad Callihan wants to know what’s going wrong:

Many times, when I’m using Extended Events, I’m filtering on an Id or procedure name in query text and tracking what’s hitting a database. In these cases, I’m assuming queries are going to complete successfully. Did you know Extended Events can be useful when you’re expecting things to go wrong? Let’s look at how we can use Extended Events to track down error messages.

You’ll get a fair amount of noise on a busy server–especially dev servers where people are writing queries and trying things out—but this is a great technique for seeing if something has gone wrong and we need to look into it before a customer reaches out.

Trying out Azure Geo-Replication

Etienne Lopes continues a series on Azure SQL DB HA/DR:

So, first of all, what is Active Geo-Replication?

Active geo-replication is a feature that lets you create a continuously synchronized readable secondary database for a primary database. The readable secondary database may be in the same Azure region as the primary, or, more commonly, in a different region. This kind of readable secondary database is also known as a geo-secondary or geo-replica.“

Read on to learn more about the topic, including how to set it up and ways to try it out.

Thoughts on Testing Stored Procedures

Erik Darling has a plan:

While most of it isn’t a security concern, though it may be if you’re using Row Level Security, Dynamic Data Masking, or Encrypted Columns, you should try executing it as other users to make sure access is correct.

When I’m writing stored procedures for myself or for clients, here’s what I do.

Click through for Erik’s guidance. The premise is couched in security testing, though much of this is functionality and performance testing Regardless, it’s a good plan.

Generating Tables from Files in Microsoft Fabric via Notebook

Dennes Torres performs a bit of ELT:

When Microsoft Fabric was born, the only method to convert files to tables was using notebooks. Nowadays we have an easy-to-use UI feature for the conversion.

As I explained on the article about lakehouse and ETL, there are some scenarios where we still need to use notebooks for the conversion. One of these scenarios is when we need table partitioning.

Let’s make a step-by-step on this blog about how to use notebooks and table partitioning.

Adding a Service Principal to a Fabric Workspace via API

Marc Lelijveld tackles a challenge:

Lately, I found myself struggling using the Power BI REST API to add a service principal to the (Fabric) workspace. After I engaged with some other folks, I managed to succeed. In this blog I will elaborate on the mistake I made and how I got it to work. For some this might be a less useful blog. Though, I still wanted to blog this even if it is for my own memory on how to do this.

Read on for the story.
