SQS消息延迟无法按预期工作 [英] SQS Message Delay Not Working As Expected

问题描述

我正在尝试延迟发送单个SQS消息.使用 https://docs.aws .amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-send-message-with-timer.html 来测试消息延迟，我看不到任何延迟.

I'm trying send individual SQS messages with a delay. Using https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-send-message-with-timer.html to test message delays, I'm not seeing any delay.

如果我在队列上设置了延迟，则该延迟将被兑现，但是对于单个消息则不会.我正在执行以下操作(全部在AWS控制台中进行):

If I set a delay on the queue, that delay is honoured, however not for individual messages. I'm doing the following (all from the AWS console):

• 打开SQS控制台，右键单击我的测试队列-确认队列的延迟值为0.
• 右键单击测试队列，然后单击发送消息"
• 添加邮件正文
• 将此邮件的延迟发送时间"设置为30秒
• 点击发送消息.
• 收到确认消息，说明您的消息已发送，将在30秒内准备好接收."

但是，当我检查CloudWatch时，我可以看到消息几乎是立即发送的.我是误解了什么，还是错过了配置中的某些内容?

However when I check CloudWatch I can see that the message was delivered almost immediately. I'm I misunderstanding something, or have I missed something in the configuration?

推荐答案

我的测试显示，发送到Lambda函数用作触发器的SQS队列的消息将立即触发Lambda函数，即使提供了延迟"设置.

My testing shows that messages sent to an SQS queue which a Lambda function is using as a trigger will immediately trigger the Lambda function, even if a Delay setting is provided.
