Patterns for real-time stream processing

A talk at Crunch Conference, Budapest, Hungary, 30 Oct 2015

Abstract

You have some streams of data, such as user activity on a website, or sensor readings from devices. Now you want to process the data and make it useful with low latency: for example, generating real-time recommendations, detecting abuse, filtering spam or predicting demand. And you want it to scale well.

Perhaps you’ve heard of distributed stream processing frameworks such as Samza, Storm or Spark Streaming, which may do what you want, but you’re not sure how to use them most effectively.

This talk will introduce some common design patterns for working with high-volume, real-time data streams. We will look at things like joining, enriching, filtering and aggregating streaming data, and we’ll explore how you might break down an application into streaming operators that do what you want.
