Draft outline details
Step by step
- Start a three-node cluster in containers (verify version before recording) and write a key.
- Isolate one node and show writes still commit on the majority side.
- Read from the isolated node and show it refuses or returns stale data depending on settings.
- Planned mistake: isolate two nodes and expect writes to continue; fix by explaining that no majority means no commits.
- Heal the partition and show the follower catching up.
