I like that idea, say after N inserts to a database/bigquery or N requests to existing service, after a file is posted to storage, or once a VM variable hits a certain trigger, kick off cloud function. Great for mini batching ETLs, log cleanup/parsing, upload possessing, cache invalidation... So many use cases.

That flexibility would be great. Hope this is on the radar! Cloud run triggers. Being able to pass the event metadata in would be great too.
