Custom, Complex Windows @Scale Using Apache Flink
100 Million members in over 190 countries leads to more than 1 Trillion events and 3 PB of data flowing through Netflix’s real-time data infrastructure each day. We’ve built a data pipeline in the cloud that reliably collects and routes these events to a variety of sinks. The data in...
Predictive Datacenter Analytics With Strymon
A modern enterprise datacenter is a complex, multi-layered system whose components often interact in unpredictable ways. Yet, to keep operational costs low and maximize efficiency, we would like to foresee the impact of changing workloads, updating configurations, modifying policies, or deploying...
Streaming SQL Foundation: Why I ❤ Streams+Tables
What does it mean to execute robust streaming queries in SQL? What is the relationship of streaming queries to classic relational queries? Are streams and tables the same thing conceptually, or different? And how does all of this relate to the programmatic frameworks like we’re all familiar...
The Power of Distributed Snapshots in Apache Flink
Come learn how Apache Flink is handles stateful stream processing and how to manage distributed stream processing and data driven applications efficiently with Flink's checkpoints and savepoints. Over the last years, data stream processing has redefined how many of us build data pipelines....
Data Decisions With Realtime Stream Processing
At Facebook, we can move fast and iterate because of our ability to make data-driven decisions. Data from our stream processing systems provide real-time data analytics and insights; the system is also implemented into various Facebook products, which have to aggregate data from many sources. In...
Panel: SQL Over Streams, Ask the Experts
Queries over streams are generally "continuous," executing for long periods of time and returning incremental results. Yet operations over streams must have the ability to be monotonic. New Generation of Stream Processing Engines has added support for Stream SQL. This AMA / panel features a...

QCon: What's the focus of your work and of the team that you're on at Facebook?
Rajesh: My team is working on stream processing, and we are part of the real-time data organization which focuses on faster, simpler, and smarter delivery of data. We want to reduce the time to results for people and our data driven products and people wait on that rely on data driven. Our organization encompasses the stream...
Read Full InterviewHuman-Centric Machine Learning Infrastructure @Netflix
Can you give an example of some of the questions you get from data scientists when you are trying to deploy models?
When it comes to common questions, as boring as it may sound, my experience is that machine learning infrastructure is much more about data than science. Most questions we get are related to data: how do I find the data I need, how do I set up the data pipeline, how do I handle the somewhat non-trivial amounts of data in python and R,...
