Google Pub/Sub API limits

Question

Are there any limits on retrieval/update APIs provided?

I was able to find these docs:

• https://cloud.google.com/pubsub/quotas : This contains info about throughputs and limits on the number of topics, subscriptions, and messages creation.
• https://cloud.google.com/free/docs/gcp-free-tier : This just says 10GB of messages per month.

What about the limits on retrieval/update APIs?

For Example: Retrieving Topic with its name, Updating a subscription.

Answer 1

In the quota page that you mentioned, you have this

All the administrative operation (list, get, update, delete,...) have a quotas to 100 ops/s
