Cassandra

This course provides an in-depth introduction to using Cassandra and with a focus on the practical aspects of working with C*. In this course, participants learn the internal architecture and CQL (Cassandra Query Language), as well as the Java API for writing Cassandra clients.

Objectives:

• At the end of Cassandra training course, participants 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:

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