Building Apache Flink Applications in Java

► TRY THIS YOURSELF: https://cnfl.io/flink-java-apps-module-1 Introduction to Flink datastream: data sources and the difference between finite and infinite data streams. Every Flink datastream starts with some type of data source (or more). This is the origin of the data. This data may be created programmatically, it may be read from a file or a database, or it may come from a streaming platform such as Apache Kafka. Depending on the nature of the source, the datastream might be finite it might be infinite. Understanding the difference can be important for implementing certain types of operations in the stream. This video will introduce a few different types of sources and discuss the difference between finite and infinite data streams.

About the course

Apache Flink is a powerful engine built for processing streaming data flows in a distributed environment. Rather than accumulating data into batches to be processed later, Apache Flink allows us to process the data as it happens, applying stateful transformations along the way. This makes it an invaluable tool for today’s streaming needs. So why Flink? Peel away the surface of a modern system and you’ll often find a mountain of data being processed. It wasn’t always this way. Not long ago applications were smaller and the data tended to be static. Processing was performed on demand whenever a query was made. If the application required upfront computation, it was done with a batch job running against a relatively small data set. Today, the data sets have grown to staggering sizes. They are too large for a simple batch job to handle. Meanwhile, users are no longer content to wait hours or even minutes for a batch job to process their data. They want results now. As a result, developers are increasingly turning to distributed streaming solutions to process data in real time. Learn how to use Flink and build Flink appications. This course will introduce students to Apache Flink through a series of hands-on exercises. Students will build a basic application in Java that will consume a collection of Apache Kafka data streams. The data will be transformed using Flink and pushed back into new Kafka topics. This simple use case will give students many of the tools they need to start building production-grade Apache Flink applications. Learn more: https://cnfl.io/flink-java-apps-module-1
