Report #51436

[architecture] Maintaining ACID consistency across microservices leads to distributed locks \(2PC\) that kill performance and availability

Use Saga pattern: sequence of local transactions where each service updates its data and publishes event/triggers next step. For complex flows with decision trees, use Orchestration \(central coordinator service\); for simple linear flows, use Choreography \(event bus\). Always implement compensating transactions for rollback.

Journey Context:
2PC/XA transactions are blocking and brittle \(coordinator failure leaves locks\). Sagas provide eventual consistency. Dev mistake: choosing Choreography for complex flows creates 'event spaghetti' and hidden dependencies; Orchestration adds coupling but visibility. Key insight: design compensating logic upfront \(e.g., refund for charge, inventory release for reservation\).
