Often our users are not aware that they are responsible for setting up and
monitoring the database they chose as the metaa-data backend.
While details of the tables and database structure of the metadata DB used
by Airflow is internal detail, the monitoring, tracking the usage, fine-tuning
and optimisation of the database configuration and detecting some cases where
database becomes a bottle neck is generally a task that Deployment Manager
should be aware of and it should be approached in a generic way - specific to
the database chosen by the Deployment Manager and it also depends a lot on the
choice of managed database if managed database is chosen by the Deployment
Manager.
This chapter makes it explicit and gives enough leads to the Deployment
Manager to be able to follow after they chose the database, it also explain the
specific parameters tha the Deployment Manager should pay attention to when
setting up such monitoring.
We also add an explanation of how Deployment Manager can setup client-side
logging of SQL queries generated by Airflow in case database access is
suspected for performance issues with Airflow, as a poor-man's version of
complete, server-side monitoring and explains caveats of such client side
configuraiton.
