Overview of this book

Modern Data Architectures with Python will teach you how to seamlessly incorporate your machine learning and data science work streams into your open data platforms. You’ll learn how to take your data and create open lakehouses that work with any technology using tried-and-true techniques, including the medallion architecture and Delta Lake. Starting with the fundamentals, this book will help you build pipelines on Databricks, an open data platform, using SQL and Python. You’ll gain an understanding of notebooks and applications written in Python using standard software engineering tools such as git, pre-commit, Jenkins, and Github. Next, you’ll delve into streaming and batch-based data processing using Apache Spark and Confluent Kafka. As you advance, you’ll learn how to deploy your resources using infrastructure as code and how to automate your workflows and code development. Since any data platform's ability to handle and work with AI and ML is a vital component, you’ll also explore the basics of ML and how to work with modern MLOps tooling. Finally, you’ll get hands-on experience with Apache Spark, one of the key data technologies in today’s market. By the end of this book, you’ll have amassed a wealth of practical and theoretical knowledge to build, manage, orchestrate, and architect your data ecosystems.

Practical lab

Our cloud team will be triggering an AWS Lambda and passing the path to the data being delivered from our ingestion tool. They have asked for a Lambda that will pass that information to your workflow, which should be parameterized. This type of request is very common and allows Databricks to be interacted with using a variety of tooling, such as AWS Step Functions and Jenkins, among others.

Solution

In this solution, we will walk you through the Python code needed to complete the tasks. There are two ways to access Databricks via the REST API – using the requests package, as shown previously, and using the Python package provided by Databricks. In my solution, I am using the Databricks package to keep things simple. I have not come across a case where the package doesn’t meet my needs, but if it’s not good enough, you can always access the REST API directly.
