MySQL Cluster on Raspberry Pi
NDB on Pi is a teaching cluster, not a capacity plan.
NDB Cluster on Raspberry Pi teaches topology with hardware you can hold: management nodes, data nodes, API/mysqld nodes, failover drills.
Transfers
- Failure-domain thinking
- SST/IST pain in miniature
- Why arbitration and quorum matter
Does not transfer
- Wi-Fi/cheap-switch network behaviour
- SD-card failure modes as “storage design”
- DataMemory/IndexMemory sizing for production
- Real concurrency headroom
Use Pis to learn failure. Size production NDB on hardware that matches documented requirements, with planned networking and arbitration.
