Report #71791

[architecture] Distributed transactions across microservices blocking resources or creating single points of failure

Use the Saga pattern with compensating transactions instead of Two-Phase Commit \(2PC\); orchestrate via choreography or orchestration, never use a distributed lock coordinator in the request path

Journey Context:
2PC requires a coordinator that locks resources until completion, creating a distributed SPOF and reducing availability \(if coordinator fails, locks persist\). Sagas split transactions into local commits with compensating actions for rollback. Compensations must be idempotent and asynchronous. Choreography reduces coupling but complicates debugging; orchestration centralizes logic but creates a bottleneck.
