I was deploying very small size Cloud Function for testing, there were errors multiple times as I was doing egress network request which were not supported on the Spark plan and some other code related errors.
I upgraded to Blaze plan and was able to deploy the function successfully. Now suddenly my Bandwidth usage under Cloud Storage shot to 412 MB (41% of 1 GB of free tier). Going through other similar questions (will Cloud Function affect Firebase Storage bandwidth usage?) I expected it to increase but is such high increase expected and how do I reduce it?
Also I found here that Cloud Storage also increases for some people: Cloud Storage increasing on deploying Cloud Function. In my case the bytes stored are still 0, can someone explain this to me?
What I am doing is a payment gateway integration on my app and they have asked some code to be run on server side (currently I am doing it on app code itself for testing). I am moving this code to cloud functions. I am just afraid if there was this much increase for this small function and how much I will end up till this goes live?
