In this chapter, you learned how to install and configure many of the tools used by data engineers. Having done so, you now have a working environment in which you can build data pipelines. In production, you would not run all these tools on a single machine, but for the next few chapters, this will help you learn and get started quickly. You now have two working databases – Elasticsearch and PostgreSQL – as well as two tools for building data pipelines – Apache NiFi and Apache Airflow.
In the next chapter, you will start to use Apache NiFi and Apache Airflow (Python) to connect to files, as well as Elasticsearch and PostgreSQL. You will build your first pipeline in NiFi and Airflow to move a CSV to a database.
