Autonomous driving with Airflow

When: (Jul-13 16:00 UTC)
-----

This talk describes how Airflow is utilized in an Autonomous driving project, originating from Munich - Germany. We describe the Airflow setup, what challenges we encountered and how we maneuvered to achieve a distributed and highly scalable Airflow setup.

One of the biggest automotive manufacturers elected to go for Airflow as an orchestration tool, in the pursuit of producing their first Level-3 autonomous driving vehicle in Germany.

In this talk, we will describe the journey of deploying Airflow on top of OpenShift using a PostgreSQL database + RabbitMQ. We will describe how we achieve high-availability for the different Airflow components. We will tackle issues related to the database performance and failover recovery for the different Airflow components in our setup. In addition, we will present the bottlenecks we encountered with (1) Airflow scheduler (especially with complex DAGs), and (2) SparkSubmitOperator. For both topics, we will describe how we mitigated them. We will also describe how we leverage OpenShift to dynamically scale our Airflow deployment based on the running workloads.

The talk will be concluded with a brief overview of future requirements and beneficial features we believe will be helpful for the community.
