Report #82882
[architecture] Handling partial failures in distributed multi-agent transactions
Implement the Saga pattern with backward recovery: each agent action has a corresponding compensating transaction; if Agent 3 fails, orchestrator triggers compensations for Agents 2 and 1 in reverse order, ensuring eventual consistency without distributed locks.
Journey Context:
ACID transactions across distributed agents require 2PC \(Two-Phase Commit\) which blocks resources and requires all agents to be available \(impractical for external APIs\). The Saga pattern accepts eventual consistency and handles failures via compensations \(e.g., if booking fails, refund payment\). Forward recovery \(retry\) works for transient errors; backward recovery \(compensate\) for permanent failures. Tradeoff: Compensations are business-logic complex \(not all actions can be undone\) and create 'dangling' states visible to users temporarily.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
