Content preview from Data Engineering with Python

Chapter 11: Building a Production Data Pipeline

In this chapter, you will build a production data pipeline using the features and techniques that you have learned in this section of the book. The data pipeline will be broken into processor groups that perform a single task. Those groups will be version controlled and they will use the NiFi variable registry so that they can be deployed in a production environment.

In this chapter, we're going to cover the following main topics:

Creating a test and production environment
Building a production data pipeline
Deploying a data pipeline in production

Creating a test and production environment

In this chapter, we will return to using PostgreSQL for both the extraction and loading of data. The data ...
