Apache Kafka Quick Start Guide

By: Raúl Estrada

Overview of this book

Apache Kafka is a great open source platform for handling your real-time data pipeline to ensure high-speed filtering and pattern matching on the ?y. In this book, you will learn how to use Apache Kafka for efficient processing of distributed applications and will get familiar with solving everyday problems in fast data and processing pipelines. This book focuses on programming rather than the configuration management of Kafka clusters or DevOps. It starts off with the installation and setting up the development environment, before quickly moving on to performing fundamental messaging operations such as validation and enrichment. Here you will learn about message composition with pure Kafka API and Kafka Streams. You will look into the transformation of messages in different formats, such asext, binary, XML, JSON, and AVRO. Next, you will learn how to expose the schemas contained in Kafka with the Schema Registry. You will then learn how to work with all relevant connectors with Kafka Connect. While working with Kafka Streams, you will perform various interesting operations on streams, such as windowing, joins, and aggregations. Finally, through KSQL, you will learn how to retrieve, insert, modify, and delete data streams, and how to manipulate watermarks and windows.

Running the SparkProcessor

To build the project, run this command from the kioto directory as follows:

$ gradle jar

If everything is OK, the output is something similar to the following:

BUILD SUCCESSFUL in 3s
1 actionable task: 1 executed
  1. From a command-line terminal, move to the Confluent directory and start it as follows:
      $ ./bin/confluent start
  1. Run a console consumer for the uptimes topic, shown as follows:
      $ ./bin/kafka-console-consumer --bootstrap-server localhost:9092 
--topic uptimes
  1. From our IDE, run the main method of the PlainProducer built in previous chapters
  2. The output on the console consumer of the producer should be similar to the following:
{"event":"HEALTH_CHECK","factory":"Lake Anyaport","serialNumber":"EW05-HV36","type":"WIND","status":"STARTING...
