Nowadays, Web3 startup teams have increasingly complex needs for handling blockchain data and are no longer satisfied with just building dashboards.

But building a stable, easy-to-use blockchain warehouse is no easy task. ethereum-etl and ethereum-etl-airflow are two excellent open-source projects. Users can get full volume data directly through ethereum-etl and build a pipeline of T+1 data through ethereum-etl-airflow. However, having them alone is just half of the story.
