Use patterns like Outbox and Transactional Session to guarantee consistency so that every message is processed correctly.
Saga Manages data consistency across microservices that have independent datastores by ensuring that services update each other through defined event or message channels. Each service performs local transactions to update its own state and publishes an event to trigger the next local transaction in the saga. If a service update fails, the saga runs compensating transactions to counteract preceding service update steps. Individual service update steps can themselves implement resiliency patterns, such as retry.
