I am a beginner. and I am sorry that my English is not good.

I am programming using firestore, firebase cloud functions(2nd gen).

I am asking about @firestore_fn.on_document_created limit of firebase cloud functions(2nd gen).

Question 1.

Is there no limit on the number of event not yet to trigger the cloud function?

For example, if there are a billion event and one instance of cloud function, do all events trigger the cloud function at least once, even if late?

Question 2.

Does request timeout mean the time from the moment the event triggers a function to the moment it completes its mission?

Or does it mean the time from the moment the event occurs to the moment the function completes its mission?

Thank you for reading my question of beginner in program.
