- This wasn’t really what I expected (implementing the Raft algorithm), but more a high-level overview of consensus algorithms, byzantine & otherwise.
- Some bits were a bit flippant and hand-wavy, but this was a lot to cover in ~30m.
- Not really sure what this was about; wouldn’t timeouts solve a lot of this? Latency might cause Raft to be slow but not incorrect.
Healrtbeat latency caused Raft to throw up false positives
- Byzantine nodes can be caused not just by actively malicious actors, but also more innocent effects, such as problems with the hardware or the network.
