Question content

In Google pub/sub, if a topic is created, we can set the retention policy

https://console.cloud.google.com/cloudpubsub

By clicking, editing, editing topic, updating

Is it possible to update this value programmatically?

I saw that the subscription level has this configuration https://github.com/googleapis/google-cloud-go/blob/main/pubsub/subscription.go#L564 But not at the topic level?

Workaround

Yes, message retention can be configured programmatically in the topic. In Go, you can set RetentionDuration in TopicConfig and pass it to CreateTopicWithConfig Do this on creation:

tc := TopicConfig{
    RetentionDuration = 168 * time.Hour
}
topic, err := c.CreateTopicWithConfig(context.Background(), "my-topic", tc)

To do this on update, set the property in TopicConfigToUpdate and pass it to Update:

topic := client.Topic("my-topic")
topicConfig, err := topic.Update(ctx, pubsub.TopicConfigToUpdate{
  RetentionDuration = 168 * time.Hour
})
