Apache Cassandra - Tutorial 6 - Partitioning, Rings and Tokens

In this tutorial we will look at partitioning, rings and tokens in Apache Cassandra. The Cassandra ring, tokens and the partitioner are used in combination to decide what node or machine in our cluster a certain record will be stored on. It is very important to understand how Cassandra partitions the data in order to get the maximum performance benefit out of Cassandra and to understand how to correctly use CQL.
