Updates to Airflow 1.10.1; See (1), (2) for some notes
Related, and additionally: configures Airflow to restore logging of
workflow steps to a console/sdtout logger, supporting the desired
ability to attach logging and monitoring to standard container
mechanisms. This does not change the behavior of also logging to the
airflow-arranged log files for steps and DAG runs.
A side effect of updating to 1.10.1 includes a major decrease in
resource usage by the Airflow scheudler process (reducing from ~ 1 core
fully consumed to less than 5% of a core consumed YMMV, but significant)
Additional adjustment downward of resources allocated, threads produced,
and frequency of polling leads to an overall significant reduction in
resource usage.
Airship note:
Because Airflow 1.10.0 and 1.10.1 use compatible versions of celery and
dag_run information, updating from 1.10.0 - 1.10.1 in place is possible
if airflow-worker pods are allowed to continue to run.
