Metadata Database: Airflow uses a SQL database to store metadata about the data pipelines being run. In the diagram above, this is represented as Postgres which is extremely popular with Airflow. Alternate databases supported with Airflow include MySQL.

1. According to the Composer architecture design Cloud SQL is the main place where all the Airflow metadata is stored. However, in order to grant authorization access from client application over the GKE cluster to the database we use Cloud SQL Proxy service. Particularly in Composer environment we can find airflow-sqlproxy* Pod, leveraging connections to Airflow Cloud SQL instance. XCom stands for “cross-communication” and allows to exchange messages or small amount of data between tasks. You can think of an XCom as a little object with the following fields: that is stored IN the metadata database of Airflow.

Apache Airflow - A platform to programmatically author, schedule, and monitor workflows - apache/airflow Se hela listan på tensorflow.org The objects in Airflow are divided into two types: SQL Alchemy - They always have a known structure. They are permanently saved to the database. Python objects e.g. DAG/BaseOperator - They can be created dynamic and they reside only in memory. They have no direct matches in the database. In the database, they only have simplified equivalents. For example, a Python function to read from S3 and push to a database is a task.

First one, it blows up metadata database and breaks concept what Airflow is — an orchestrator that should be minimally involved in execution and data storage. Second, not everything can be stored. Basically, XCom data is pickle and pickles have its limits as well.

Notice that serializing with pickle is disabled by default to avoid RCE exploits/security issues. Olaoye Anthony Somide. Jan 13 · 6 min read.

The Airflow metadata database stores configurations, such as variables and connections, user information, roles, and policies. It is also the Airflow Scheduler's source of truth for all metadata regarding DAGs, schedule intervals, statistics from each run, and tasks. …
