Requirements of a Distributed Messaging Queue’s Design
Establish the functional and non-functional requirements for designing a reliable distributed messaging queue. Understand why single-server queues are inadequate for modern distributed systems. This foundation guides architectural decisions for scalability and durability.
Requirements
A distributed messaging queue stores data across multiple machines. The design must satisfy the following functional and non-functional requirements.
Functional requirements
Clients must be able to perform the following actions:
Queue creation: Clients create a queue and define parameters such as the queue name,
queue size The maximum number of messages a queue can hold. For example, Amazon SQS has an unlimited standard queue size but limits inflight messages to 120,000.
