fifo - 如何使 Amazon sqs 消息遵守 FIFO

Question

是否有某种方法可用于在真正的 FIFO 中使用 Amazon SQS 消息？我尝试从配置延迟消息传递，但这没有帮助。

Answer 1

亚马逊SQS刚刚获得FIFO Queues with Exactly-Once Processing & Deduplication :

Today we are making SQS even more powerful and flexible with support for FIFO (first-in, first-out) queues. We are rolling out this new type of queue in two regions now, and plan to make it available in many others in early 2017.

These queues are designed to guarantee that messages are processed exactly once, in the order that they are sent, and without duplicates. [...]

[emphasis mine]

正如所强调的，这些新的 FIFO SQS 队列将使任何特殊注意事项在真正的 FIFO 中使用 Amazon SQS 消息变得不必要，但尚未在所有 SQS regions 中可用。 [最初仅在美国东部(俄亥俄州)和美国西部(俄勒冈州)]。
