What this pull request accomplishes:

  • move GCC layers and Primary key dictionaries to Airflow variables
  • Dynamic DAG generation for bigdata/ptc GCC layers using Airflow variable which stores credentials, deployment
  • added mat view refreshes to Airflow variable: easier addition of new aggregations!

Issue(s) this solves:

What, in particular, needs to reviewed:

  • I couldn't think of an obvious way to make mat view aggregations their own Airflow tasks in a dynamic way so I just added them to the pull_layers task. Thoughts?

What needs to be done by a sysadmin after this PR is merged

  • change data_scripts link in Morbius

Can we make the mapped task's name as the layer's name? for refreshing the materialized view, I'm thinking we could use a trigger function on the table instead 🤔

Oh I'll remove this, it was for testing (instead of execute).

Thanks for reminding me that morbius's airflow version doesn't have mapped tasks naming yet :meow_headache: This looks good! refreshing mat view as a tasks as good as well.
