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.

Using FoundationDB and the FDB Record Layer to Build CloudKit - Scott Gray, Apple

This talk is about the features of FoundationDB and the Record Layer that help build CloudKit, Apple’s cloud storage system for structured data. Scott Gray, a software engineer at Apple focuses on three key areas where FoundationDB and the Record Layer have unlocked large benefits for CloudKit. First, FoundationDB’s arbitrary multi-key ACID transactions have allowed implement advanced secondary indexing at scale, including our recently-developed transactional full-text search system.

NuGraph: GraphDB as a Cloud Service Built Upon JanusGraph and FoundationDB - Jun Li & Hieu Nguyen, eBay

Ebay has built a GraphDB cloud service called NuGraph, which is based on JanusGraph. FoundationDB is chosen as the JanusGraph’s storage plugin, because of its high-performance and distributed transaction support. Jun Li and Hieu Nguyen from eBay present the GraphDB architecture, and focus on how they deploy and manage FoundationDB in Kubernetes, how they improve JansGraph query performance in a cross-data center environment, how they bulk load the graph into FoundationDB with its transactional support, and how they secure the 3-tier cloud service with limited security support from FoundationDB.
