Learn to author, schedule and monitor data pipelines through practical examples using Apache Airflow

What you'll learn

Create plugins to add functionalities to Apache Airflow.

Using Docker with Airflow and different executors

Master core functionalities such as DAGs, Operators, Tasks, Workflows, etc

Understand and apply advanced concepts of Apache Airflow such as XCOMs, Branching and SubDAGs.

The difference between Sequential, Local and Celery Executors, how do they work and how can you use them.

Use Apache Airflow in a Big Data ecosystem with Hive, PostgreSQL, Elasticsearch etc.

Install and configure Apache Airflow

Think, answer and implement solutions using Airflow to real data processing problems

Requirements

VirtualBox must be installed - A VM of 3Gb will have to be downloaded

At least 8 gigabytes of memory

Some prior programming or scripting experience. Python experience will help you a lot but since it's a very easy language to learn, it shouldn't be too difficult if you are not familiar with.

Description

Apache Airflow is an open-source platform to programmatically author, schedule and monitor workflows. If you have many ETL(s) to manage, Airflow is a must-have.In this course you are going to learn everything you need to start using Apache Airflow through theory and pratical videos. Starting from very basic notions such as, what is Airflow and how it works, we will dive into advanced concepts such as, how to create plugins and make real dynamic pipelines.
