What is the overhead of dbt's dynamic model generation ?

Hello, I would like to know what happens in the backend when I generate model dynamically from the schema ?

  • Does it parse the schema file and generate sql statements ?
  • If it parse the schema file, does it parse the whole file or just the part for which I want to generate the model ?

What is the overhead that I need to consider in general when generating model dynamically from the schema ?
