The Datasource client uses environment variables available in the workspace to automatically authenticate your identity.
To override this behavior, see Custom Authentication.
Assuming a Datasource named redshift-test has been configured with valid credentials for the current user:
from domino.data_sources import DataSourceClient
# instantiate a client and fetch the datasource instance
redshift = DataSourceClient().get_datasource("redshift-test")
query = """
SELECT
firstname,
lastname,
age
FROM
employees
LIMIT 1000
"""
# res is a simple wrapper of the query result
res = redshift.query(query)
# to_pandas() loads the result into a pandas dataframe
df = res.to_pandas()
# check the first 10 rows
df.head(10)
