Fast Data Processing Systems with SMACK Stack

By: Raúl Estrada

Overview of this book

SMACK is an open source full stack for big data architecture. It is a combination of Spark, Mesos, Akka, Cassandra, and Kafka. This stack is the newest technique developers have begun to use to tackle critical real-time analytics for big data. This highly practical guide will teach you how to integrate these technologies to create a highly efficient data analysis system for fast data processing. We’ll start off with an introduction to SMACK and show you when to use it. First you’ll get to grips with functional thinking and problem solving using Scala. Next you’ll come to understand the Akka architecture. Then you’ll get to know how to improve the data structure architecture and optimize resources using Apache Spark. Moving forward, you’ll learn how to perform linear scalability in databases with Apache Cassandra. You’ll grasp the high throughput distributed messaging systems using Apache Kafka. We’ll show you how to build a cheap but effective cluster infrastructure with Apache Mesos. Finally, you will deep dive into the different aspect of SMACK using a few case studies. By the end of the book, you will be able to integrate all the components of the SMACK stack and use them together to achieve highly effective and fast data processing.

Preface

Cluster


Now we are ready to program with the Apache Kafka publisher-subscriber messaging system. First, a few terminologies:

In Kafka, there are three types of clusters:

  • Single node - single broker
  • Single node - multiple broker
  • Multiple node - multiple broker

A Kafka cluster has five main actors:

  • Broker: The server - a Kafka cluster has one or more physical servers where each one may have one or more server processes running.Each server process is called a broker. The topics live on the broker processes.
  • Topic: The queue is a category or feed name in which messages are published by the message producers. Topics are partitioned, and each partition is represented by an ordered immutable messages sequence. The cluster has a partitioned log for each topic. Each message in the partition has a unique sequential ID called offset.
  • Producer: These publish data to topics by choosing the appropriate partition in the topic. To achieve load balancing, the message allocation to the topic partition can be done...
