Preview Features

Preview features have been implemented and tested in Snowflake; however, full usability and corner-case handling may not be complete yet. We do not warranty the use of these features against defects that may produce unexpected or undesired results. Additionally, we may change the behavior of features while they are in preview. If we change the behavior of a preview feature, we do our best to notify users before making the change, but we do not guarantee to always pre-announce changes.

Attention

Preview features are provided primarily for evaluation and testing purposes. They should not be used in production systems or with production data.

For more details about the usage of preview features, see the Snowflake Preview Terms of Service.

Preview Availability

Availability is determined on a per-feature basis:

Open:

Most preview features are Open, meaning they are enabled by default for all accounts and, therefore, openly available for use.

On Request:

Some preview features are provided On Request, particularly in the early stages of the preview period. To request access to these features for your account, you must contact Snowflake.
