The fastest way to deploy your Serverless app - serverless function deployment - how to

When deploying code for you lambda function, you could just run "sls deploy" but that re-deploys your whole application.

A far better approach is to run 'sls deploy function -f {function name}` to just deploy a single function code.

Hi, I would like to understand someting - inside your file function.ts you hold all possible functions in your project. So every time that a lambda function will run (from a cold start for exemple) all the functions must to be read even though only one will be used? Imagine that in a large scale of milions of lambdas... how many code will be read without be used? How many miliseconds or seconds could you save in scale?
