Learning Apache Flink

Overview of this book

<p>With the advent of massive computer systems, organizations in different domains generate large amounts of data on a real-time basis. The latest entrant to big data processing, Apache Flink, is designed to process continuous streams of data at a lightning fast pace.</p> <p>This book will be your definitive guide to batch and stream data processing with Apache Flink. The book begins with introducing the Apache Flink ecosystem, setting it up and using the DataSet and DataStream API for processing batch and streaming datasets. Bringing the power of SQL to Flink, this book will then explore the Table API for querying and manipulating data. In the latter half of the book, readers will get to learn the remaining ecosystem of Apache Flink to achieve complex tasks such as event processing, machine learning, and graph processing. The final part of the book would consist of topics such as scaling Flink solutions, performance optimization and integrating Flink with other tools such as ElasticSearch.</p> <p>Whether you want to dive deeper into Apache Flink, or want to investigate how to get more out of this powerful technology, you’ll find everything you need inside.</p>

Preface

Supported algorithms


To get started with FlinkML, we first need to add the following Maven dependency:

<!-- https://mvnrepository.com/artifact/org.apache.flink/flink-ml_2.11 --> 
<dependency> 
    <groupId>org.apache.flink</groupId> 
    <artifactId>flink-ml_2.11</artifactId> 
    <version>1.1.4</version> 
</dependency> 

Now let's try to understand the supported algorithms and how to use those.

Supervised learning

Flink supports three algorithms in the supervised-learning category. They are as follows:

  • Support Vector Machine (SVM)

  • Multiple linear regression

  • Optimization framework

Let's get started learning about them one at a time.

Support Vector Machine

Support Vector Machines (SVMs) are supervised learning models, which analyze the data solving classification and regression problems. It helps classify objects into one category or another. It is non-probabilistic linear classification. There are various examples...
