upgrade process:
The database upgrade may take a while depending on the number of DAGs in
the database and the volume of history
stored in the database for task history, xcom variables, etc.
+ In our testing, we saw that performing the Airflow database upgrade from
Airflow 1.10.14 to Airflow 2.0
+ took between two to three minutes on an Airflow database on PostgreSQL
with around 35,000 task instances and
+ 500 DAGs.
For a faster database upgrade and for better overall performance, it is
recommended that you periodically archive
the old historical elements which are no longer of value.
