How does Rails handle distributed transaction patterns in microservices?

Rails uses saga patterns, compensating transactions, and eventual consistency instead of ACID across services.

In microservices architectures, Rails cannot rely on traditional ACID transactions across services. Instead, it uses the Saga pattern where each service performs a local transaction and emits events. If a later step fails, compensating actions are triggered to undo previous operations. This can be implemented via event brokers (Kafka/RabbitMQ) or orchestration services. Rails typically uses Sidekiq or event-driven services to coordinate steps.
