Use Snowflake as a governed data and compute environment where its supported capabilities fit the project. Define the analytical objective, data permissions and evaluation plan before selecting tools.
Prepare and explore data with SQL, Snowpark and supported notebooks, using bounded queries and reproducible datasets. Record source versions, transformations and feature definitions. Separate training and evaluation correctly, and fit preprocessing without leaking evaluation information.
Snowflake ML provides native feature, training, registry and inference capabilities. Choose warehouse or container-based execution according to the supported model, dependencies, memory and latency needs. Resources and budgets are finite; large data does not remove the need for sampling, efficient joins and capacity planning.
An external function calls code outside Snowflake and sends its arguments through the configured integration. It is not proof that training happens locally or that no data leaves the platform. If using an external model endpoint, review its access, retry semantics, data handling, availability and cost.
Deploy a versioned model through a supported registry/serving path, validate input/output contracts and least-privilege invocation, and compare against the previous model. Secure Data Sharing can distribute approved data or supported objects; it is not a generic mechanism that deploys every model to another organization.
Monitor quality with delayed ground truth, feature freshness, drift, latency and cost. Keep rollback and retraining procedures tied to measured conditions. Retraining on newer data does not automatically improve accuracy.
