Cloud Run Admin API read/write request quota limits

[Adriano Matos]

I am trying to set quota limits to my Cloud Run services, but I'd like to get a better understanding on some terms before I start playing with numbers I'm unsure about.

I was wondering what exactly is a "read request" with Cloud Run? Is states here in the documentation:

"The number of API reads per 60 seconds per project. This is not the number of read requests to your Cloud Run services, which is not limited."

but I still can't wrap my brain around what this means. Can I think of it synonymously to a single run within a Cloud Run instance? If that is true, then what would be considered a "write request"?

Here is an example: say I have a Cloud Run instance integrated with Pub/Sub. So whenever a message gets pushed into a topic, an instance of my Cloud Run service is created. Say there are 5 messages, which should trigger 5 requests to my Cloud Run service. Would the number of read requests in this example be 5?

API write requests are essentially the calls made from your application to the Cloud Run API [1] to update the disk. These would be calls of the write operations to the disk (in bytes/sec). Since the number of resources in Cloud Run are limited, quotas are established for Cloud Run that encompasses API rate limits.
