Overview of this book

In the world of ever-changing data and schemas, it is important to build data pipelines that can auto-adjust to changes. This book will help you build scalable data platforms that managers, data scientists, and data analysts can rely on. Starting with an introduction to data engineering, along with its key concepts and architectures, this book will show you how to use Microsoft Azure Cloud services effectively for data engineering. You'll cover data lake design patterns and the different stages through which the data needs to flow in a typical data lake. Once you've explored the main features of Delta Lake to build data lakes with fast performance and governance in mind, you'll advance to implementing the lambda architecture using Delta Lake. Packed with practical examples and code snippets, this book takes you through real-world examples based on production scenarios faced by the author in his 10 years of experience working with big data. Finally, you'll cover data lake deployment strategies that play an important role in provisioning the cloud resources and deploying the data pipelines in a repeatable and continuous way. By the end of this data engineering book, you'll know how to effectively deal with ever-changing data and create scalable data pipelines to streamline data science, ML, and artificial intelligence (AI) tasks.

Developing a data aggregation pipeline

Before we start developing the aggregation pipeline, we need to deploy the following Azure resources:

Figure 8.3 – Electroniz aggregation pipeline

In the following section, we will be creating the aggregation pipeline highlighted in the preceding diagram.

Preparing the Azure resources

Follow these steps to start the Azure resource deployment process:

  1. We will start by creating a new namespace in Azure Data Lake Storage for the gold layer.

    I mentioned earlier that storage account names in Azure are globally unique. Throughout this exercise, we will be using traininglakehouse as the storage account name. You will need to edit it as per the account name that you created:

    STORAGEACCOUNTNAME="traininglakehouse"
    GOLDLAYER="gold"
    az storage fs create -n $GOLDLAYER --account-name $STORAGEACCOUNTNAME --only-show-errors

    This results in the following output:
