We are triggering DAGs in Google Cloud Composer via Airflow's REST interface.
https://airflow.apache.org/docs/apache-airflow/stable/deprecated-rest-api-ref.html
We can see that the DAGs triggered this way get Run IDs with manual__ prefix, e.g.:
Run Id
manual__2021-06-25T05.52.31.103391+00.00
When we trigger these DAGs from Cloud Functions want to differentiate these executions from the manually executed DAGs (triggered from UI) or from automatically scheduled executions (triggered by cron/scheduling criteria).
Question: Is it possible to mark the executions triggered via REST API other than manual__?
Sidenote: currently we are using Composer with Airflow 1.x, but we are planning to change to Airflow 2.x as soon as the Composer supports it.
