2019-11-01 In this database or data warehouse conception, the metadata repository exists in one place, organized by a particular scheme. In a standard data warehouse diagram, the metadata repository is depicted as a centralized, single container storing all the system’s metadata, operating to the side along with other data warehouse functions. Testing Airflow is hard There's a good reason for writing this blog post - testing Airflow code can be difficult. It often leads people to go through an entire deployment cycle to manually push the trigger button on a live system. Only after can they verify their Airflow code. This is a painfully long process […] 2019-10-18 2020-01-04 Would there be any benefit to using a cloud-based database like snowflake for this?

The metadata database stores the state of tasks and workflows. The scheduler uses the DAGs definitions, together with the state of tasks in the metadata database, and decides what needs to be executed. The executor is a message queuing process (usually Celery) which decides which worker will execute each task.

Alternate databases supported with Airflow include MySQL. Airflow’s operation is built atop a Metadata Database which stores the state of tasks and workflows (i.e. DAGs). The Scheduler and Executor send tasks to a queue for Worker processes to perform. For Apache Airflow, a database is required to store metadata information about the status of tasks.
