WebApr 11, 2024 · At first, producer sends 1 and consumer receives 1. And then, the consumer is delayed for 100ms and producer sends message from 2 to 10 to the message queue during this time. The consumer then extracts from the message queue and get value of 10 instead of 2. So I'm assuming that the message queue is not in FIFO order. WebWe use FIFO queues and set the message group id in the SendMessageRequest for the queue's in our application.
