Key concepts

Provide users with more context on the tools and services used in the sample. Explain some of the code that is being used and how services interact with each other.

Cassandra Counters

A counter is a special column used to store an integer that is changed in increments. Counters are useful for many data models. Some examples:

1) To keep track of the number of web page views received on a company website 2) To keep track of the number of games played online or the number of players who have joined an online game
