Airbyte is an open-source data integration engine that helps you consolidate your data in your data warehouses, lakes and databases.

Airbyte

I know Airbyte will integrate with DBT and Airflow. However it seems like I need to use those right now. *What is the best practice for me to manage DBT and Airflow projects?* So that in the future I will integrate to Airbyte when it is ready

You should be able to install and setup your DBT projects completely separately from Airbyte

They won't have direct dependencies between the tools other than sharing same credentials to access the warehouse for now

I am guessing Airbyte might provide some helper files (sources definitions?) to make life easier in DBT later

For Airflow, I'm not sure at this time but coordinating Airbyte's own simple scheduler (or an integrated airflow right in airbyte) with external airflow instance should be resolved so you can probably move forward with setting up a separate airflow server too
