The protocol must maintain safety guarantees even when coordinators crash, participants fail, networks partition, or messages are lost. **Scenario 1: Participant Fails Before Voting** If a participant crashes before sending its vote, the coordinator will timeout waiting and treat this as a VOTE_ABORT. The transaction aborts. Upon recovery, the participant finds no PREPARED record and simply discards any incomplete work. **Scenario 2: Participant Fails After Voting COMMIT** This is more complex. The participant has durably logged PREPARED and may have sent VOTE_COMMIT. Upon recovery: 1. It finds a PREPARED record in its log 2. It must contact the coordinator (or other participants) to learn the outcome 3. It then commits or aborts based on the global decision **Scenario 3: Coordinator Fails After Collecting Votes** This is the **blocking scenario**. If the coordinator crashes after collecting votes but before broadcasting the decision: - Participants who voted COMMIT are stuck in PREPARED state - They cannot commit (don't know if others voted ABORT) - They cannot abort (others might have committed) - They must hold locks and wait for coordinator recovery73:Td21,// Recovery Protocol for Coordinator and Participants class CoordinatorRecovery
