Suppose I have an airflow dag file that creates a graph like so...
def get_current_info(filename)
current_info = {}
<fill in info in current_info relevant for today's date for given file>
return current_info
files = [
get_current_info("file_001"),
get_current_info("file_002"),
....
]
for f in files:
<some BashOperator bo1 using f's current info dict>
<some BashOperator bo2 using f's current info dict>
....
bo1 >> bo2
....
Since these values in the current_info dict that is used to define the dag
changes periodically (here, daily), I would like to know by what process /
schedule the dag definition gets updated. (I print the current_info values
each run and values appear to be updating, but curious as to how and when
exactly this happens).
When does an airflow dag definition get evaluated? referenced anywhere in
the docs?
