Apache Airflow version

Other Airflow 2/3 version (please specify below)

If "Other Airflow 2/3 version" selected, which one?

3.1.0

What happened?

We have a DAG which each time it is triggered would create 3 DAG versions. Question is why is this happening , as the impact is that the serialized_dag table is growing and would require clean up

What you think should happen instead?

would like to understand how does DAG version being triggered , we would not like to have multiple versions

How to reproduce

in this example i am not sure what triggered the DAG versions being increased , but basically we are using some custom operators and looping through a list to generate python operators

Operating System

RHEL
