Move past recipe execution by deliberately inducing internal faults and simulating runtime crashes
● Recommended Breakthrough Drill
Deterministic Partition Simulation Drill
Force packet drops and observe leader election timeout state machines manually. Prevent the framework from running on happy-path defaults.
// Inject deterministic 1200ms latency to node-b
iptables -A INPUT -p tcp --dport 7001 -m statistic --mode random --probability 0.4 -j DROP
Mental Model Verification Gate
Draw the state machine transition on paper before inspecting logs. If your predicted timeout behavior differs from actual Raft election term increments, pinpoint the internal invariant violation.
