什么是“交付模式"?在AMQP中? [英] What is the "delivery mode" in AMQP?

问题描述

我了解有2种选择:

• 非持久"
• 持久"

但这实际上是什么意思?

But what does this actually mean?

非持久性"，如:如果没有使用者，则AMQP结构将尝试传递消息，该消息将被丢弃吗?

"Non-persistent" as in : the AMQP fabric will try to deliver the message if there are no consumers, the message will be dropped?

持久性"，如:AMQP将重试该消息，直到消费者接受为止?

"Persistent" as in : AMQP will retry the message until a consumer accepts it??

推荐答案

传递给持久"队列的标记为持久"的消息将记录到磁盘.如果发生崩溃，则会恢复持久队列以及崩溃之前存储的所有持久性消息.

Messages marked as 'persistent' that are delivered to 'durable' queues will be logged to disk. Durable queues are recovered in the event of a crash, along with any persistent messages they stored prior to the crash.
