Lessons Learned from the Migration to Apache Airflow - Radek Maciaszek, Skimlinks*

Radek Maciaszek presents his learnings from the migration of machine learning and big data processing pipelines to Apache Airflow.

He highlights how they use Airflow to power their company big data infrastructure where they analyze hundreds of terabytes of data. Examples will cover the building of the ETL pipeline and use of Airflow to manage the machine learning Spark pipeline workflow.

The talk covers the basic Airflow concepts and show real-life examples of how to define your own workflows in the Python code. It finishes with more advanced topics related to Apache Airflow, such as adding custom task operators, sensors and plugins as well as best practices and both the pros and cons of this tool.

Kubernetizing Big Data and ML Workloads at Uber - Mayank Bansal & Min Cai, Uber

Uber relies on Big Data and ML to make business critical decisions such as pricing, trip ETA, etc. Today, those workloads such as Hive and Spark are running on YARN. To save millions of dollars by efficient use of cluster resources, Uber is planning to use Kubernetes to co-locate BigData/ML and micro-service workloads.

This talk will covers the following:
- Learnings of running large-scale BigData/ML on Kubernetes with Peloton
- Colocation of mixed workloads
- Federation across zones
- Feature and API parity with YARN
