Overview

The goal of this course is to enable technical students new to Cassandra to begin working with Cassandra in an optimal manner. Throughout the course students will learn to:
Understand the Big Data needs that C* addresses
Be familiar with the operation and structure of C*
Be able to install and set up a C* database
Use the C* tools, including cqlsh, nodetool, and ccm (Cassandra Cluster Manager)
Be familiar with the C* architecture, and how a C* cluster is structured
Understand how data is distributed and replicated in a C* cluster
Understand core C* data modeling concepts, and use them to create well-structured data models
Be familiar with the C* eventual consistency model and use it intelligently
Be familiar with consistency mechanisms such as read repair and hinted handoff
Understand and use CQL to create tables and query for data
Know and use the CQL data types (numerical, textual, uuid, etc.)
Be familiar with the various kinds of primary keys available (simple, compound, and composite primary keys)
Be familiar with the C* write and read paths
Understand C* deletion and compaction

Description

The Cassandra (C*) database is a massively scalable NoSQL database that provides high availability and fault tolerance, as well as linear scalability when adding new nodes to a cluster. It has many powerful capabilities, such as tunable and eventual consistency, that allow it to meet the needs of modern applications, but also introduce a new paradigm for data modeling that many organizations do not have the expertise to use in the best way.Introduction to Cassandra is a hands-on course designed to teach attendees the basics of how to create good data models with Cassandra. This technical course has a focus on the practical aspects of working with C*, and introduces essential concepts needed to understand Cassandra, including enough coverage of internal architecture to make good decisions. It is hands-on, with labs that provide experience in core functionality. Students will also explore CQL (Cassandra Query Language), as well as some of the anti-patterns' that lead to non-optimal C* data models and be ready to work on production systems involving Cassandra.
