在 SQS 中查找某些消息 [英] Finding certain messages in SQS
问题描述
我知道 SQS 不是为此而构建的，但我很好奇是否可以在队列中找到满足某些条件的消息?
I know SQS ain't build for that, but I'm curious is it possible to find messages in a queue that meet some criteria?
我可以循环拉取消息，在消息正文中搜索某种模式(甚至不需要反序列化它们)，并过滤我需要的消息.但是，有可能以无限循环结束——当我到达队列末尾时，我阅读的第一条消息将返回队列......
I can pull messages in a loop, search the message bodies for some pattern (without even deserializing them), and filter the messages I needed. But then it is possible to end up with an infinite loop - the first messages I read will be back to the queue by the time when I reach the end of the queue...
扩展消息的可见性是可能的，但我如何确切知道扫描整个队列需要多长时间，以及我应该扩展可见性多长时间?如果我在那里实际上有一万条消息怎么办?
Extending visibility of the messages possible, but how do I know exactly how long it will take to scan the entire queue, and for how long should I extend the visibility? What if I have literally ten thousand messages in there?
这里有什么解决方法吗?我需要扫描队列中的一些消息，然后删除那些......
Is there any workaround here? I need to scan the queue for some messages, and delete those...
推荐答案
简短回答:否.
队列是为诸如任务之类的事情而设计的.一台机器从队列中抓取一个新任务(即消息)，执行该任务，然后删除该任务.
Queues are designed for things like tasks. A machine grabs a new task (i.e., message) from the queue, executes the task, then deletes the task.
如果您尝试搜索消息以过滤它们，我不禁怀疑您是否使用了错误的工具来完成这项工作......
If you're trying to search the messages to filter them, I can't help but wonder if you're using the wrong tool for the job…
