Overview of this book

Apache Storm is a real-time Big Data processing framework that processes large amounts of data reliably, guaranteeing that every message will be processed. Storm allows you to scale your data as it grows, making it an excellent platform to solve your big data problems. This extensive guide will help you understand right from the basics to the advanced topics of Storm. The book begins with a detailed introduction to real-time processing and where Storm fits in to solve these problems. You’ll get an understanding of deploying Storm on clusters by writing a basic Storm Hello World example. Next we’ll introduce you to Trident and you’ll get a clear understanding of how you can develop and deploy a trident topology. We cover topics such as monitoring, Storm Parallelism, scheduler and log processing, in a very easy to understand manner. You will also learn how to integrate Storm with other well-known Big Data technologies such as HBase, Redis, Kafka, and Hadoop to realize the full potential of Storm. With real-world examples and clear explanations, this book will ensure you will have a thorough mastery of Apache Storm. You will be able to use this knowledge to develop efficient, distributed real-time applications to cater to your business needs.

Producing Apache log in Kafka using Logstash


As explained in Chapter 8, Integration of Storm and Kafka, Kafka is a distributed messaging queue and can integrate very well with Storm. In this section, we will show you how we can use Logstash to read the Apache log file and publish it into the Kafka Cluster. We are assuming you already have the Kafka Cluster running. The installation steps of the Kafka Cluster are outlined in Chapter 8, Integration of Storm and Kafka.

Installation of Logstash

Before moving on to the installation of Logstash, we are going to answer the questions: What is Logstash? Why are we using Logstash?

What is Logstash?

Logstash is a tool that is used to collect, filter/parse, and emit the data for future use. Collect, parse, and emit are divided into three sections, which are called input, filter, and output:

  • The input section is used to read the data from external sources. The common input sources are File, TCP port, Kafka, and so on.
  • The filter section is used to parse the...
