我们可以在AWS SQS FIFO队列中更新消息吗? [英] Can we update messages in AWS SQS FIFO Queue?

问题描述

我们可以向AWS SQS Queue发送消息或从AWS SQS Queue接收消息，但是我们可以更新SQS Queue中已经存在的消息内容吗?如果可能的话，怎么办?

We can send/receive messages to/from AWS SQS Queue, But Can we update message content which is already in SQS Queue ? If possible , How ?

推荐答案

一旦消息已发送到SQS队列(标准或FIFO)，则该消息是不可变的.此外，不可能通过其ID向SQS询问特定消息.

Once a message has been sent to an SQS queue (standard or FIFO), the message is immutable. Additionally, it isn't possible to ask SQS for a specific message by its ID.

该消息在被消费者接收之前基本上是不可访问的.

The message is essentially inaccessible until received by a consumer.

(在AWS控制台中查看消息似乎是一个例外，但并非如此-控制台充当使用者，接收消息，然后重置其可见性超时，以便它们返回队列以进行后续重新发送. )

(Viewing messages in the AWS console might seem to be an exception, but it isn't -- the console acts as a consumer, receives messages, and then resets their visibility timeout so they return to the queue for subsequent redelivery.)
