The second half of Chapter 7 answers a question every data team hits eventually: how do you run live dashboards AND historical reports without building two completely separate systems? Then it gets practical with orchestration and a hands-on Airflow lab.

Pipeline Orchestration With Airflow, DAGs, and Data Transformations

This is Part 2 of Chapter 7, continuing from batch and streaming basics.

In Part 1, we covered how batch and streaming pipelines move data around. But here is the thing: having a pipeline is one thing. Making sure all its parts run in the right order, at the right time, without you babysitting it? That is orchestration. And this is where Chapter 7 gets really practical.
