Reliable Delivery vs At Least Once Delivery
Developers should learn and apply Reliable Delivery when building systems that require high data integrity, such as financial transactions, healthcare applications, or real-time analytics, where even minor data loss can lead to significant errors or compliance issues meets developers should use at least once delivery when building systems where message loss is unacceptable, such as financial transactions, order processing, or audit logging, as it prioritizes reliability over exactly-once semantics. Here's our take.
Reliable Delivery
Developers should learn and apply Reliable Delivery when building systems that require high data integrity, such as financial transactions, healthcare applications, or real-time analytics, where even minor data loss can lead to significant errors or compliance issues
Reliable Delivery
Nice PickDevelopers should learn and apply Reliable Delivery when building systems that require high data integrity, such as financial transactions, healthcare applications, or real-time analytics, where even minor data loss can lead to significant errors or compliance issues
Pros
- +It is essential in scenarios involving distributed architectures, microservices communication, and IoT devices, where network unreliability or failures must be mitigated to maintain system functionality and trust
- +Related to: tcp, message-queues
Cons
- -Specific tradeoffs depend on your use case
At Least Once Delivery
Developers should use At Least Once Delivery when building systems where message loss is unacceptable, such as financial transactions, order processing, or audit logging, as it prioritizes reliability over exactly-once semantics
Pros
- +It is essential in scenarios with network partitions, producer/consumer failures, or when using asynchronous messaging systems like Apache Kafka or RabbitMQ
- +Related to: distributed-systems, message-queues
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Reliable Delivery if: You want it is essential in scenarios involving distributed architectures, microservices communication, and iot devices, where network unreliability or failures must be mitigated to maintain system functionality and trust and can live with specific tradeoffs depend on your use case.
Use At Least Once Delivery if: You prioritize it is essential in scenarios with network partitions, producer/consumer failures, or when using asynchronous messaging systems like apache kafka or rabbitmq over what Reliable Delivery offers.
