Hands-On Big Data Modeling

By: James Lee, Tao Wei, Suresh Kumar Mukhiya

Overview of this book

Modeling and managing data is a central focus of all big data projects. In fact, a database is considered to be effective only if you have a logical and sophisticated data model. This book will help you develop practical skills in modeling your own big data projects and improve the performance of analytical queries for your specific business requirements. To start with, you’ll get a quick introduction to big data and understand the different data modeling and data management platforms for big data. Then you’ll work with structured and semi-structured data with the help of real-life examples. Once you’ve got to grips with the basics, you’ll use the SQL Developer Data Modeler to create your own data models containing different file types such as CSV, XML, and JSON. You’ll also learn to create graph data models and explore data modeling with streaming data using real-world datasets. By the end of this book, you’ll be able to design and develop efficient data models for varying data sizes easily and efficiently.

Aerospike

Aerospike is one of several NoSQL databases architectures that has been developed for high-speed performance, scalability, and reliability. Like Redis, this is also a key-value pair architecture, and is optimized for flash storage. The Aerospike database is written in C and has three layers: the data layer, a self-managed distribution layer, and a cluster-aware client layer. The distribution layer is replicated across the datacenters to enforce consistency.

Some of the important features of Aerospike are summarized as follows:

  • Use of hybrid memory: Aerospike utilizes flash storage in parallel on one machine to perform reads at sub-millisecond latencies at a very high throughput in the presence of a heavy write load. The use of an SSD drive or flash drive enforces high vertical scale-up.
  • Aerospike has a great ability for planning and scaling up for cluster management...
