Managing Data Pipelines using Airflow

Submitted Nov 30, 2016

Enterprise data originates from various sources. There are various business rules and processes that govern how that data can be consumed. A significant part of the IT/Data Engineering team is spent on writing and scheduling jobs, monitoring and troubleshooting the issues.

Airflow is a platform to programmatically author, schedule and monitor workflows. (

The various tasks in the workflow(s) are configured as a Directed Acyclic Graph. This talk covers how Airflow is used to establish better workflows for data engineering and enable scalable Data Analytics.


  1. Existing challenges in data engineering - creating/monitoring/troubleshooting workflows
  2. Introduction to Airflow
  3. Main advantages of Airflow
  4. Tasks as DAG
  5. Airflow in practice - case study
  6. Dynamic pipeline generation
  7. UI demo (dashboards)
  8. Data Engineering at Scale
  9. What Airflow is NOT !
  10. Brief overview of what other options exist in Python
  11. Closing thoughts
