We plan on deprecating 4 tables:
* `mobile_apps_uniques_daily` not updated since 2021-02-18
* `mobile_apps_uniques_monthly` still active (on 2023-05-01)
* `mobile_apps_session_metrics` not updated since 2018-03-20
* `mobile_apps_session_metrics_by_os` still active (on 2023-05-07)
Our plan is to:
[x] Pause the computation jobs (there's only 2 active, one in Oozie, one in Airflow)
[x] Create MR to remove the Airflow DAG https://gitlab.wikimedia.org/repos/data-engineering/airflow-dags/-/merge_requests/379
[x] Create a patch to remove the refinery-source Spark code https://gerrit.wikimedia.org/r/c/analytics/refinery/source/+/919357
[x] Drop the hive table but keep the data (we can recreate the tables easily)
[x] Wait for 90 days, and in case nobody has asked about the data...
[x] Remove the code from refine and airflow-dags
[x] Delete the old data altogether
[] Delete the Airflow DAG
