3. Use Cases for Reliable-Message Eventual Consistency

• Suitable for businesses that require eventual consistency, have low time sensitivity, and where the distributed transaction can only succeed rather than fail, such as awarding points after registration or coupons after login.
• Multiple services use multiple data sources, and the data sources do not have to be DBs.

4. Implementations of Reliable-Message Eventual Consistency

4.1. Local Message Table

4.2. Transaction Messages
