The statement regarding the retention of event messages according to policy is spot on. In Alibaba Cloud’s Message Service (MS), event messages can be configured to follow specific retention policies. This means that you can set rules determining how long messages should be stored before they are automatically deleted. This flexibility allows organizations to manage their data effectively, ensuring they keep relevant information accessible for a predetermined period while also complying with data retention regulations or practices.

Understanding the implications of message retention is crucial for architects who design communication systems using Alibaba Cloud services. It enables effective data management strategies and ensures that resources are allocated efficiently.

In contrast, other statements do not accurately represent the features of the Message Service. Event notification messages are not stored permanently, allowing for a more dynamic approach to message handling. Also, the consumer type is not limited to Queue only, as various mechanisms support different consumer formats. Lastly, event notifications do not require manual sending; they can be automated based on events, aiding in real-time communication.
