Best way at present to create/update/delete multiple documents at one go

At present I am using cloud function and loop the create document function.

But I need to know whether 120 requests per minute limit is there for cloud functions too???

Also awaiting for each call and then sending another create document request takes some time.Is there any other option to do

REQUEST:- Create a direct function like create documents,update documents and delete documents so that it doesn't require the use of creating cloud function.

P.S. I am using python for cloud functions.

Thank you.
