Airflow is entirely free to use and completely customizable. And created a database where this data is going to be deposited into. This allows for writting code that instantiate pipelines dynamically. Data Collected from the API is moved to landing zone s3 buckets. NOTE: We recently gave an Airflow at WePay talk to the Bay Area Airflow meetup group.The video and slides are both available.. Our last post provided an overview of WePay’s data warehouse. Airflow also provides hooks for the pipeline author to define their own parameters, macros and templates.
