> Can someone check if there is growth in the `dag_version` or
`serialized_dag` tables in your environment when memory use climbs? Row count
is sufficient.
Hello,
Since we had to roll back the Airflow version in our production environment,
I executed the query in the NPRD environment. This environment currently runs
only four DAGs: two scheduled every 5 minutes and two scheduled once per day.
The results are as follows:
airflow_db=# select count(*) from dag_version;
count
-------
16635
(1 row)
airflow_db=# select count(*) from serialized_dag;
count
-------
16635
(1 row)
Additionally, while analyzing the same DAG
(index_ibm_cloud_metrics_in_elasticsearch), we observed that in some runs, two
DAG versions were generated, whereas in other runs only one was created,
despite the code remaining unchanged during the corresponding timestamps:
