rubenbriones opened a new issue, #29202:
URL: https://github.com/apache/airflow/issues/29202
### Apache Airflow version
2.5.1
### What happened
When modifying the trigger rule of a dynamic task mapping to ONE_SUCCESS,
the task only creates one task mapped, and not all the N mapped task that it
should create. If i leave the trigger rule to the default ALL_SUCCESS,
everything works fine.
### What you think should happen instead
I want to set the ONE_SUCCESS trigger rule so that the mapped tasks that
succeed keep executing theirs downstream tasks, no matter what other tasks have
failed.
### How to reproduce
```py
import pendulum
from airflow.decorators import dag, task
@dag(
schedule="0 0 * * MON-FRI",
start_date=pendulum.datetime(2023, 1, 1, tz="UTC"),
catchup=False,
max_active_runs=1,
)
def etl():
@task
def get_symbols():
res = [('A', 1, 111), ('B', 2, 222)]
return res
@task
def extract(symbol_info, data_interval_end=None):
# Do some work...
return symbol_info
@task(trigger_rule="one_success")
def transform(symbol_info, data_interval_end=None):
# Do some work...
return symbol_info
@task(trigger_rule="one_success")
def load(symbol_info, data_interval_end=None):
# Do some work...
return symbol_info
# DAG
symbols = get_symbols()
raw_symbols_data = extract.expand(symbol_info=symbols)
clean_symbols_data = transform.expand(symbol_info=raw_symbols_data)
load.expand(symbol_info=clean_symbols_data)
symbols_ib()
```
