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.

Stream processing

Streaming is a very useful mode of processing data and can come with a large amount of complexity. One thing a purist must consider is that Spark doesn’t do “streaming data” – Spark does micro-batch data processing. So, it will load whatever the new messages are and run a batch process on them in a continuous loop while checking for new data. A pure streaming data processing engine such as Apache Flink will only process one new load of “data.” So, as a simple example, let’s say there are 100 new messages in a Kafka queue; Spark would process all of them in one micro-batch. Flink, on the other hand, would process each message separately.

Spark Structured Streaming is a DataFrame API on top of the normal Spark Streaming, much like the DataFrame API sits on the RDD API. Streaming DataFrames are optimized just like normal DataFrames, so I suggest always using structured streaming over normal Spark Streaming. Also, Spark...
