What does the post-hook's primary function serve in the context of dbt?

The primary function of a post-hook in dbt is to execute additional SQL commands after a model has been built. Post-hooks are set up to run SQL statements after the dbt model runs its transformation logic. This allows for flexibility in workflow management, enabling users to perform tasks such as updating related tables, inserting logs, or manipulating data that is dependent on the success of the model execution.

By using post-hooks, analytics engineers can automate tasks that are necessary to maintain data integrity or trigger additional processes without having to manually execute those SQL commands every time a model is run. This enhances efficiency and ensures that additional actions are consistently executed in conjunction with the model builds.
