Google Cloud Platform: Is there a way to ignore Pub/Sub messages if the cloud function is already processing?

php editor Youzi brings you an introduction to Google Cloud Platform. During cloud function processing, if we want to ignore Pub/Sub messages, is there a solution? Google Cloud Platform provides a simple and effective way to achieve this requirement. This article will introduce in detail how to ignore Pub/Sub messages in Google Cloud Platform, making your processing of cloud functions more flexible and efficient.

Question content

I am very new to Google Cloud Platform and am currently making some Cloud Functions in Go. I'm wondering if a cloud function that is a subscriber to a topic can ignore messages that are already being processed?

Essentially, my system sends a "completion" message at some point, which starts a cloud function, I want to make it so that if the topic receives another completion message, it doesn't start another subscription or function instance, but ignore the message.

Workaround

I'm not sure if I can do this locally using a Cloud Function.

You may consider using state to handle such use cases.

For example, in Google Cloud there are memorystore and Redis to store the messages you receive.

In your cloud function , you can use the Python Redis client to access the cache. You can add a filter to only process messages that are not present in the cache.
