Stream Processing and Beyond with Apache Flink

Getting started with real-time, low-latency data processing

Topic: Data
Bowen Li

Time is value—and it’s missing in your legacy big data infrastructure. Businesses now must generate more value from their real-time data to offer better service and interact with their customers faster. This requires shifting from big data, from batch-oriented processing with high latency of hours or even days, to stream processing, where data is processed as it flows in with superlow latency in a scalable, fault-tolerant fashion. And Apache Flink is driving this trend, helping businesses grow and thrive at a faster pace through its streaming-first architecture and key features and capabilities.

Join expert Bowen Li to learn how to leverage Flink’s building blocks and develop Flink applications. You’ll understand how Flink works and get hands-on experience using it to process streaming data in real time, with lessons you can immediately apply in your own work.

What you'll learn-and how you can apply it

By the end of this live online course, you’ll understand:

  • How the Apache Flink community works
  • Stream processing and Flink fundamental concepts
  • What makes Flink fast, reliable, and scalable
  • How to architect a native real-time data platform
  • What the Apache Flink community has been actively working on beyond stream processing, in fields like machine learning, AI, and serverless computations

And you’ll be able to:

  • Set up a local Flink development and testing environment
  • Run an end-to-end application with Flink SQL and Kafka
  • Write Flink applications using the DataStream API with Java and Flink SQL

This training course is for you because...

  • You’re a data engineer or software engineer who’s eager to build real-time data pipelines and platforms.
  • You’re a product manager or business manager who wants to understand the use cases and functionalities offered by Flink and stream processing.
  • You want to become an expert in stream processing, real-time ETL, and Apache Flink.


  • A basic understanding of Java programming and SQL
  • Familiarity with big data tools and platforms like Hadoop
