In college we had a database class going to Oracle, MySQL and other SQL based databases. In the last two weeks of the course we were tasked with looking at NoSQL databases.
I was interested in this NoSQL. How does it work? How is it different? What makes it better? To answer this, I created Cassandra Server on a Raspberry Pi. I learned a lot when getting Cassandra working my Raspberry Pi.
I really wanted to have a cluster of Pi’s all running Cassandra nodes but between work, other classes, and the time I already put into this project I never got around to it.
