Split-brain
What is a split-brain scenario in a replicated system?
Options
- 1A network partition lets two subsets each elect a leader and accept writes independently, diverging and risking data corruption
- 2A single node runs out of disk and stops accepting writes, forcing a manual failover to a healthy peer node
- 3A replica lags behind the leader, so reads from it return stale but still self-consistent committed data
- 4A cache returns stale data after an eviction, so the clients observe values from an older write generation
