I am trying to get a list of datasets from a catalog file i have created and pass them in as inputs of a single node to combine them and ultimately run the pipeline on airflow using the kedro-airflow plugin
This works on the cli with kedro run but seems to fail in airflow and I am not sure why:
#my_pipeline/pipeline.py
def create_pipeline(**kwargs):
conf_loader = ConfigLoader(['conf/base'])
conf_catalog = conf_loader.get('catalog-a*')
datasets = [key for key, value in conf_catalog.items()]
return Pipeline([
node(
func=combine_data,
inputs=datasets,
outputs="combined_data",
name="combined_data"
),
...#other nodes
])
The error I am getting on airflow looks something like this: Broken dag: Given configuration path either does not exist or is not a valid directory: 'conf/base'
This is a Kedro config loader error for sure but i can't seem to figure out why the only error occurs when running the pipeline via airflow. From what I have been reading mixing in the code API is not advised. Is this the right way pass in a list of datasets?
Edit
My catalog is basically a list of Sql query datasets:
dataset_1:
type: pandas.SQLQueryDataSet
sql: select * from my_table where created_at >= '2018-12-21 16:00:00' and partner_id=1
credentials: staging_sql
dataset_2:
type: pandas.SQLQueryDataSet
sql: select * from my_table where created_at >= '2019-08-15 11:55:00' and partner_id=2
credentials: staging_sql
I think it might fail because kedro run is running this from its root directory where it can find the conf/base but the create_pipeline function is under
my_pipeline
directory so kedro ConfigLoader cannot find that. I think another way I've done this in the past is, to passcatalog: DataCatalog
like this:def create_pipeline(catalog: DataCatalog = None, * *kwargs) -> Pipeline:
Then you can iterate over or do:
datasets = catalog.datasets
.
