Data Engineering with AWS

By: Gareth Eagar

Overview of this book

Written by a Senior Data Architect with over twenty-five years of experience in the business, Data Engineering for AWS is a book whose sole aim is to make you proficient in using the AWS ecosystem. Using a thorough and hands-on approach to data, this book will give aspiring and new data engineers a solid theoretical and practical foundation to succeed with AWS. As you progress, you’ll be taken through the services and the skills you need to architect and implement data pipelines on AWS. You'll begin by reviewing important data engineering concepts and some of the core AWS services that form a part of the data engineer's toolkit. You'll then architect a data pipeline, review raw data sources, transform the data, and learn how the transformed data is used by various data consumers. You’ll also learn about populating data marts and data warehouses along with how a data lakehouse fits into the picture. Later, you'll be introduced to AWS tools for analyzing data, including those for ad-hoc SQL queries and creating visualizations. In the final chapters, you'll understand how the power of machine learning and artificial intelligence can be used to draw new insights from data. By the end of this AWS book, you'll be able to carry out data engineering tasks and implement a data pipeline on AWS independently.

The AWS Glue/Lake Formation data catalog

As discussed previously, the AWS Glue catalog is a technical data catalog that can capture some business attributes using key/value tags. For example, you can have a key called data_owner and an associated value as a tag on each table in the catalog.

Within AWS, there are two services for interacting with the data catalog. So far, we have only discussed the AWS Glue service, but the AWS Lake Formation service also provides an interface for the same catalog.

It is important to understand that there is only a single data catalog, but that both Glue and Lake Formation provide an interface to the catalog. For example, if you set zone:curated as a table property on the film_category table in curatedzonedb using the Glue console, you will see that same property set when viewing the table using Lake Formation.

Here, we can see the table details for the film_category table in the AWS Glue console, and we can see that one of the tags on this...
