connector with Snowflake's custom OAuth, follow these steps:
1. Install the necessary package:
Ensure you have the prefect-snowflake
package installed:
sh
pip install prefect-snowflake
2. Define your block with OAuth credentials:
Configure a SnowflakeCredentials
block with the appropriate parameters, specifying authenticator="oauth"
and providing the OAuth token.
Here's an example of how to set this up in code:
python
from prefect_snowflake import SnowflakeCredentials
from prefect.blocks.system import Secret
# Load or create your OAuth token as a secret
oauth_token = Secret.load("MY_OAUTH_TOKEN")
snowflake_credentials_block = SnowflakeCredentials(
user="your_snowflake_user",
account="your_snowflake_account",
authenticator="oauth",
token=oauth_token
)
snowflake_credentials_block.save(name="my-snowflake-credentials", overwrite=True)
# Use these credentials in your tasks
connection = snowflake_credentials_block.get_client()
3. Use the block in your Prefect flow:
When creating your flows, load the block and use it to get the Snowflake client:
python
from prefect import flow, task
from prefect_snowflake import SnowflakeCredentials
@task
def query_snowflake():
snowflake_credentials_block = SnowflakeCredentials.load("my-snowflake-credentials")
connection = snowflake_credentials_block.get_client()
# Execute your query here
@flow
def my_flow():
query_snowflake()
my_flow()
