Working with Apache Cassandra: Using Collection & User-defined Fields

Apache Cassandra does not support joins which means that data is inherently denormalized. That gives rise to the need for collection fields such as sets maps and lists as well as for user-defined types that allow the table creator to encapsulate related fields. Begin this course by working with set map and list types. Then focus on user-defined types and counter fields. Finally you’ll learn how to work with CSV and JSON data – including reading data from and writing data to a CSV file and displaying query results in JSON format. Upon completion youll be able to enumerate and contrast collection fields in Cassandra; define and use set map and list types; leverage user-defined types and counters; and work with JSON and CSV data and the COPY command.
