I have a some EC2 servers pulling work off of a SQS queue. Occasionally, they encounter a situation where the can't finish the job. I have the process email me of the condition. As it stands now, the message stays "in flight" until it times out. I would like for the process to immediately release it back to the queue after the email is sent. But, I'm not sure how to accomplish this. Is there a way? If so, can you please point me to the call or post a code snippet.

我正在使用Python 2.7.3和Boto 2.5.2.

推荐答案

如果您已经阅读了一条消息，并且出于某种原因决定不希望对其进行处理，而是希望将其立即提供给其他读者.在队列中，您可以简单地使用boto中Message对象的change_visibility方法将该消息的visibility timeout设置为零.有关详细信息，请参见《 SQS开发人员指南》 .

If you have read a message and decide, for whatever reason, that you do not want to process it and would rather make it immediately available to other readers of the queue, you can simply set that message's visibility timeout to zero using the change_visibility method of the Message object in boto. See The SQS Developer's Guide for details.
