Linked Services in Azure Data Factory

In the previous post, we looked at datasets and their properties. In this post, we will look at linked services in more detail. How do you configure them? What are the authentication options for Azure services? And how do you securely store your credentials?

Let’s start by creating a linked service to an Azure SQL Database. Yep, that linked service you saw screenshots of in the previous post. Mhm, the one I sneakily created already so I could explain using datasets as a bridge to linked services. That one 😅

Datasets in Azure Data Factory

In the previous post, we looked at the copy data activity and saw how the source and sink properties changed with the datasets used. In this post, we will take a closer look at some common datasets and their properties.

Let’s start with the source and sink datasets we created in the copy data wizard!

Dataset Names

First, a quick note. If you use the copy data tool, you can change the dataset names by clicking the edit button on the summary page…

Copy Data Activity in Azure Data Factory

In the previous post, we went through Azure Data Factory pipelines in more detail. In this post, we will dig into the copy data activity. How does it work? How do you configure the settings? And how can you optimize performance while keeping costs down?

Copy Data Activity

The copy data activity is the core (*) activity in Azure Data Factory.

(* Cathrine’s opinion 🤓)

You can copy data to and from more than 90 Software-as-a-Service (SaaS) applications (such as Dynamics 365 and Salesforce), on-premises data stores (such as SQL Server and Oracle), and cloud data stores (such as Azure SQL Database and Amazon S3). During copying, you can define and map columns implicitly or explicitly, convert file formats, and even zip and unzip files – all in one task.

Yeah. It’s powerful! But how does it really work?

Pipelines in Azure Data Factory

In the previous post, we used the Copy Data Tool to copy a file from our demo dataset to our data lake. The Copy Data Tool created all the factory resources for us: pipelines, activities, datasets, and linked services.

In this post, we will go through pipelines in more detail. How do we create and organize them? What are their main properties? Can we edit them without using the graphical user interface?

How do I create pipelines?

So far, we have created a pipeline by using the Copy Data Tool. There are several other ways to create a pipeline.

On the Home page, click on the New → Pipeline dropdown menu, or click on the Orchestrate shortcut tile:

In the previous post, we looked at the different Azure Data Factory components. In this post, we’re going to tie everything together and start making things happen. Woohoo! First, we will get familiar with our demo datasets. Then, we will create our Azure Data Lake Storage Account that we will copy data into. Finally, we will start copying data using the Copy Data Tool.

Demo Datasets

First, let’s get familiar with the demo datasets we will be using. I don’t know about you, but I’m a teeny tiny bit tired of the AdventureWorks demos. (I don’t even own a bike…) WideWorldImporters is at least a little more interesting. (Yay, IT joke mugs and chocolate frogs!) But! Let’s use something that might be a little bit more fun to explore.

Let me present… *drumroll* 🥁
