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.

Kafka architecture

Kafka is an open source distributed streaming platform designed to scale to impressive levels. Kafka can store as much data as you have storage for, but it shouldn’t be used as a database. Kafka’s core architecture is composed of five main ideas – topics, brokers, partitions, producers, and consumers.

Topics

For a developer, a Kafka topic is the most important concept to understand. Topics are where data is “stored.” Topics hold data often called events, which means that the data has a key and a value. Keys in this context are not related to a database key that defines uniqueness, but they can be used for organizational purposes. The value is the data itself, which can be in a few different formats such as strings, JSON, Avro, and Protobuf. When your data is written to Kafka, it will have metadata; the most important will be the timestamp.

Working with Kafka can be confusing because the data isn’t stored in a database...
