Understand limitations in the Snowflake Native App Framework¶

Known Limitations¶

The Snowflake Native App Framework has limitations, including:

• Temporary tables or stages are not supported.

• Some Streamlit features are not supported. See Unsupported Streamlit Features for details.

• The Snowflake Native App Framework does not support failover for business continuity. For example, adding an application package to a replication group or failover group is not supported.

Known limitations in Snowflake Native Apps with Snowpark Container Services¶

Snowflake Native Apps with Snowpark Container Services have the following limitations:

• Apps with containers are only supported on specific AWS and Azure commercial regions. See Support for private connectivity, VPS, and government regions for information on support for private connectivity, VPS, and government regions.

• Sessions used in connections from containers, for example using the Python connector, are limited to the application owner role. See Snowpark Container Services: Additional considerations for services and jobs for additional information.

• A maximum of 5 compute pools per application is allowed.

• Cross-Cloud Auto-Fulfillment is only supported on Amazon Web Services and Microsoft Azure (preview) with the following limitation:

  • There is a 100GB limit for each file within the image repository.

• Using the LOG_LEVEL and TRACE_LEVEL properties in the manifest.yml file to set the logging and trace level for for a container is not supported. Instead, use the spec.logExporters property in the service specification file.

  See spec.logExporters field (optional) for more information.

Limitations on government regions¶

The following limitations apply to Snowflake Native App Framework support for government regions:

• Only AWS GovCloud is currently supported in the following regions:

  • US Gov West 1 (FedRAMP High Plus)

  • US Gov East 1 (FedRAMP High Plus)

  • US East (Commercial Gov - N. Virginia)

• US Gov Virginia is currently not supported.

• Providers publishing apps from government regions can only share listings within the same organization.

Limitations on Virtual Private Snowflake (VPS)¶

The following limitations apply to Snowflake Native App Framework support for Virtual Private Snowflake (VPS):

• The Snowflake Native App Framework and Streamlit are not enabled by default in Virtual Private Snowflake. To use the Snowflake Native App Framework or Streamlit in VPS, contact Snowflake Support.

• If Streamlit is not enabled in the VPS deployment, consumers cannot use the Python Permission SDK to manage privileges and references.

• Sharing an app from a VPS account to an account outside the VPS is only supported within the same organization. To share an app outside the current organization, contact Snowflake Support.

• Only private listings are supported for applications published inside the VPS.

• Consumers in the VPS can enable event sharing for an app. However, log messages and trace events are not shared unless the provider has an event table within the VPS.

• Because the Snowflake Marketplace interface is not available in VPS, providers and consumers must manage listings by using SQL. For additional information, see About managing listings using SQL.
