Architecting Data-Intensive Applications

By: Anuj Kumar

Overview of this book

<p>Are you an architect or a developer who looks at your own applications gingerly while browsing through Facebook and applauding it silently for its data-intensive, yet ?uent and efficient, behaviour? This book is your gateway to build smart data-intensive systems by incorporating the core data-intensive architectural principles, patterns, and techniques directly into your application architecture.</p> <p>This book starts by taking you through the primary design challenges involved with architecting data-intensive applications. You will learn how to implement data curation and data dissemination, depending on the volume of your data. You will then implement your application architecture one step at a time. You will get to grips with implementing the correct message delivery protocols and creating a data layer that doesn’t fail when running high traffic. This book will show you how you can divide your application into layers, each of which adheres to the single responsibility principle. By the end of this book, you will learn to streamline your thoughts and make the right choice in terms of technologies and architectural principles based on the problem at hand.</p>

Kafka streams


Kafka streams is a concept built on top of Kafka's producer and consumer APIs. It is a client library for building applications and micro services, where data is stored within the Kafka cluster. In simple terms, Kafka streams is a client library for processing and analyzing data stored in Kafka. Kafka streams is built on the stream processing concepts of distinguishing an event from its processing, support for windowing, as well as a simple yet efficient management and real time querying of the application's state.

Here are some of the highlights of Kafka Streams:

  • Simple and lightweight client library that can be used with any Java-based system
  • No external dependencies, except dependency on Apache Kafka itself, thereby simplifying your overall deployment architecture
  • Provides capabilities for fault-tolerant local state enabling very fast and stateful operations such as aggregations and windowing
  • Supports exactly-once processing guarantees, which means that an event or message will...
