即使将确认截止日期设置为 600 秒，Pub/Sub 也会在 10 秒后重新发送消息。如何克服这个问题？

[英]Pub/Sub re-sending message after 10 sec even setting ack deadline 600 sec. How to overcome this issue?

原文 2022-07-29 09:02:19 1 1 google-cloud-platform/ publish-subscribe/ google-cloud-pubsub

I'm using Pub/Sub for message delivery and I have set the ack.我正在使用 Pub/Sub 进行消息传递，并且我已经设置了 ack。 deadline 600 sec which is maximum but still If I'm not able to process that record within 10sec then It re-sends the same message again.截止日期 600 秒，这是最大值，但仍然如果我无法在 10 秒内处理该记录，那么它会再次重新发送相同的消息。 Because of this, It's delivering a duplicate message.因此，它传递了重复的消息。

So, Is there anything else I need to configure in Pub/Sub subscription?那么，我还需要在 Pub/Sub 订阅中配置什么吗？ I have also configured the Retry policy as Immediate, should I set it so exponential back off?我还将重试策略配置为立即，我应该将其设置为指数级后退吗？
