I'm reading Dumps/Airflow on wikitech. It talks about DAGs. What is a DAG? The usual meaning (Directed Acyclic Graph) doesn't make any sense in this context.
It is actually Directed Acyclic Graph. Just in context of apache airflow: https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/dags.htm...

Apache Airflow is a widely used scheduling / orchestration service. It's well documented at https://airflow.apache.org/ where you can find details on DAGs https://airflow.apache.org/docs/apache-airflow/stable/index.html#dags. Our wikitech docs are more about how we deploy and maintain it. Basically, tasks inside an airflow orchestration until form a directed acyclic graph.

I was confused about this too when working on documentation for our data platform! FWIW, there is a glossary at https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Airflow/Developer_.... It seems like that Developer Guide page has become a bit buried compared to the content at https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Airflow. I just added a link to it on the DAG page Andre referenced, and I modified the Airflow page to try to make the link to https://wikitech.wikimedia.org/wiki/Data_Platform/Systems/Airflow/Developer_... more obvious.
