- Seamless Deployment: Deploy apps directly to the Snowflake Marketplace or within your organization with a few clicks.
2.3 Enhanced Collaboration and Monetization
Snowflake Native Apps foster a collaborative ecosystem:
- Data Sharing: Easily incorporate shared datasets into your apps for enhanced model training.
- App Marketplace: Distribute your intelligent apps to a wide audience through the Snowflake Marketplace.
- Monetization Opportunities: Create new revenue streams by selling your apps or data products.
2.4 Real-time Inference and Scoring
Native Apps excel at delivering real-time intelligence:
- Low-latency Compute: Co-location of data and compute enables fast inference times.
- Serverless Execution: Apps run on-demand without provisioning or managing infrastructure.
- Automatic Scaling: Snowflake handles scaling to meet varying inference loads.
2.5 Built-in Governance and Versioning
Native Apps provide robust governance features out-of-the-box:
- Access Controls: Leverage Snowflake's fine-grained access controls for data and app functionality.
- Auditing: Built-in query history and access logs for compliance and monitoring.
- Versioning: Easily manage and deploy different versions of your intelligent apps.
3. Building Intelligent Apps with Snowflake Native Apps
Let's explore how to build an intelligent app using Snowflake Native Apps:
3.1 Developing the ML Model
First, we'll create a simple churn prediction model using Snowpark for Python:
from snowflake.snowpark.session import Sessionfrom snowflake.snowpark.functions import colfrom sklearn.ensemble import RandomForestClassifierimport joblib# Create Snowflake sessionsession = Session.builder.configs(connection_parameters).create()# Load and prepare datadf = session.table("CUSTOMER_DATA").to_pandas()X = df.drop("CHURN", axis=1)y = df["CHURN"]# Train modelrf_model = RandomForestClassifier(n_estimators=100, random_state=42)rf_model.fit(X, y)# Save modeljoblib.dump(rf_model, 'churn_model.joblib')
3.2 Packaging the App
Next, we'll create a Native App that uses this model:
-- Create a stored procedure for model inferenceCREATE OR REPLACE PROCEDURE PREDICT_CHURN(CUSTOMER_ID NUMBER)RETURNS TABLE (CHURN_PROBABILITY FLOAT)LANGUAGE PYTHONRUNTIME_VERSION = '3.8'PACKAGES = ('snowflake-snowpark-python', 'scikit-learn', 'joblib')HANDLER = 'predict_churn'AS$$import joblibfrom snowflake.snowpark.session import Sessiondef predict_churn(session, customer_id): model = joblib.load('churn_model.joblib') customer_data = session.sql(f"SELECT * FROM CUSTOMER_FEATURES WHERE ID = {customer_id}").to_pandas() churn_prob = model.predict_proba(customer_data)[0][1] return [(float(churn_prob),)]def main(session: Session) -> str: return "Churn Prediction App Initialized"$$;-- Create the Native AppCREATE APPLICATION CHURN_PREDICTOR USING PROCEDURE PREDICT_CHURN RETURNS TABLE (CHURN_PROBABILITY FLOAT);
3.3 Deploying and Using the App
Deploy the app to your Snowflake account or the Marketplace. Users can then utilize the app like this:
-- Use the Churn Predictor AppCALL CHURN_PREDICTOR.PREDICT_CHURN(123456);
4. Advanced Features of Snowflake Native Apps for Intelligent Applications
4.1 Real-time Data Processing
Leverage Snowflake's Streams and Tasks for real-time data processing within your app:
-- Create a stream to capture new customer dataCREATE STREAM customer_stream ON TABLE customers;-- Create a task to process new data and update predictionsCREATE TASK update_predictionsWAREHOUSE = compute_whSCHEDULE = '1 minute'WHEN SYSTEM$STREAM_HAS_DATA('customer_stream')ASBEGIN MERGE INTO customer_predictions p USING customer_stream s ON p.customer_id = s.customer_id WHEN MATCHED THEN UPDATE SET p.churn_probability = (SELECT * FROM TABLE(CHURN_PREDICTOR.PREDICT_CHURN(s.customer_id))) WHEN NOT MATCHED THEN INSERT (customer_id, churn_probability) VALUES (s.customer_id, (SELECT * FROM TABLE(CHURN_PREDICTOR.PREDICT_CHURN(s.customer_id))));END;
4.2 Integrating External Services
Native Apps can integrate with external services via Snowflake's External Functions:
-- Create an API integrationCREATE API INTEGRATION api_integration API_PROVIDER = aws_api_gateway API_AWS_ROLE_ARN = 'arn:aws:iam::123456789012:role/snowflake-external-func-role' ENABLED = true API_ALLOWED_PREFIXES = ('https://myapigateway.execute-api.us-west-2.amazonaws.com/prod/');-- Create an external functionCREATE EXTERNAL FUNCTION enrich_customer_data(customer_id varchar) RETURNS VARIANT API_INTEGRATION = api_integration AS 'https://myapigateway.execute-api.us-west-2.amazonaws.com/prod/enrich_customer';-- Use the external function in your appCREATE OR REPLACE PROCEDURE ENHANCED_PREDICT_CHURN(CUSTOMER_ID NUMBER)RETURNS TABLE (CHURN_PROBABILITY FLOAT, ENRICHED_DATA VARIANT)LANGUAGE PYTHONAS$$import joblibfrom snowflake.snowpark.session import Sessiondef enhanced_predict_churn(session, customer_id): model = joblib.load('churn_model.joblib') customer_data = session.sql(f"SELECT * FROM CUSTOMER_FEATURES WHERE ID = {customer_id}").to_pandas() churn_prob = model.predict_proba(customer_data)[0][1] enriched_data = session.sql(f"SELECT enrich_customer_data('{customer_id}') AS ENRICHED").collect()[0]['ENRICHED'] return [(float(churn_prob), enriched_data)]$$;
