Accelebrate's Introduction to Cassandra 3 for Developers training course provides an in-depth introduction to using Cassandra and with a focus on the practical aspects of working with C*. Students learn the internal architecture and CQL (Cassandra Query Language), as well as the Java API for writing Cassandra clients.

  • This course includes coverage of Cassandra 3.x, but is also suitable for users of Cassandra 2.

Skills Gained

All students will:

  • Understand the 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
  • Use data replication and eventual consistency intelligently
  • Understand and use CQL to create tables and query for data
  • Know and use the CQL data types (numerical, textual, uuid, etc.)
  • Understand the various kinds of primary keys available (simple, compound, and composite primary keys)
  • Use more advanced capabilities like collections, counters, secondary indexes, CAS (Compare and Set), static columns, and batches
  • Be familiar with the Java client API
  • Use the Java client API to write client programs that work with C*
  • Build and use dynamic queries with QueryBuilder
  • Understand and use asynchronous queries with the Java API

Prerequisites

Students should have reasonable Java experience and some knowledge of databases.

Provided good amount of material and a great instructor to teach the material.

ExitCertified was a great. They gave me all the materials and information I needed ahead of time to prepare for the course.

The class was very vast paced however the teacher was very good at checking in on us while giving us time to complete the labs.

Although there seemed to be too many links for the course, everything worked smoothly.

Class was easy to sign up for and ExitCertified provided very good communication
