“We’re amidst the Big Data Zeitgeist era in which data comes at us fast, in myriad forms and formats at intermittent intervals or in a continuous stream, and we need to respond to streaming data immediately. This need has created a notion of writing a streaming application that’s continuous, reacts and interacts with data in real-time. We call this continuous application.
In this tutorial we’ll explore the concepts and motivations behind the continuous application, how Structured Streaming Python APIs in Apache Spark™ enable writing continuous applications, examine the programming model behind Structured Streaming, and look at the APIs that support them.
Through presentation, code examples, and notebooks, I will demonstrate how to write an end-to-end Structured Streaming application that reacts and interacts with both real-time and historical data to perform advanced analytics using Spark SQL, DataFrames and Datasets APIs.
You’ll walk away with an understanding of what’s a continuous application, appreciate the easy-to-use Structured Streaming APIs, and why Structured Streaming in Apache Spark is a step forward in developing new kinds of streaming applications.
This tutorial will be both instructor-led and hands-on interactive session. Instructions in how to get tutorial materials will be covered in class.
