Multi-Datacenter Cassandra on 32 Raspberry Pis #piday #RaspberryPi @Raspberry_Pi
Thanks so much to Daniel for sending in this project! Read more here.
Here at Datastax, my fellow intern Daniel Chin and I built a 32 node DataStax Enterprise cluster running on Raspberry Pi’s! We are showcasing the always on, fault tolerant nature of Cassandra by letting anybody take down an entire data center with the press of a Big Red Button in our lobby.
Being able to withstand a data center going down is not just an edge case, it is an absolute necessity for the highly available applications Cassandra powers. While the cloud is far more flexible for production use, nothing beats a big shiny hardware display for a demo.
Our main goal for this project was to take the abstract concept of fault tolerance and make it something you can see in action and interact with. We built upon the work of Travis Price and the DataStax Sales Engineering team, who pioneered the use of Raspberry Pi’s to demonstrate Cassandra.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
