Ruslan Dautkhanov updated AIRFLOW-1176:
---------------------------------------
Description:
Gantt visualization is brojen.
It used to work on a ~month older Airflow snapshot.
See attached screenshot.
!Gantt.png!
- It just doesn't show anything (it used to show all >40 operators correctly)
- time scale is shifted so almost no visible
It is a `@once` DAG.. I noticed Airflow has a number of issues around `@once`
DAG, so decided to mention.
{noformat}
main_dag = DAG(
dag_id = 'DISCOVER-Oracle-Load-Mar2017-v1',
default_args = default_args, # dafeult
operators' arguments - see above
user_defined_macros = dag_macros, # I do not get different
between
## params = dag_macros, # user_defined_macros
and params
#
start_date = datetime.now(), # or e.g.
datetime(2015, 6, 1)
# 'end_date' = datetime(2016, 1, 1),
catchup = False, # Perform
scheduler catchup (or only run latest)?
# -
defaults to True
schedule_interval = '@once', #
'@once'=None?
# doesn't
create multiple dag runs automatically
concurrency = 3, # task
instances allowed to run concurrently
max_active_runs = 1, # only one
DAG run at a time
dagrun_timeout = timedelta(days=4), # no way
this dag should ran for 4 days
orientation = 'TB', # default
