Understand limitations in the Snowflake Native App Framework¶

This topic provides information about the limitations of Snowflake Native Apps.

Known limitations¶

Snowflake Native Apps have the following known limitations:

• Temporary tables or stages are not supported.
• Some Streamlit features are not supported. See Unsupported Streamlit features for details.
• Running a Streamlit app on a container runtime is in preview and has additional limitations. For details, see Limitations for container runtimes in an app.
• Snowflake Native Apps do not support failover for business continuity. For example, adding an application package to a replication group or failover group is not supported.
• Storage lifecycle policies aren’t supported in Snowflake Native Apps.
• Snowflake ML functions such as Top Insights aren’t supported in Snowflake Native Apps.

Application package version and stage size limits¶

The following size limits apply to application package versions in Snowflake deployments on AWS, Azure, and Google Cloud:

The file limit is in GB (decimal). The stage limit is in GiB (binary).

The AWS and Azure limits apply to deployments on these clouds, including government regions and AWS China regions.

Application package versions that exceed the Google Cloud limits aren’t supported in Google Cloud deployments. Snowflake doesn’t block you from creating such a version on AWS or Azure, but replicating it to a Google Cloud deployment might be slow or fail intermittently. If you distribute your app to Google Cloud deployments, keep each file under 5 GB and the version stage under 5 GiB. To check sizes before you add a version, run LIST @<stage>/<path> and add up the size column.

Known limitations in Snowflake Native Apps with Snowpark Container Services¶

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

• Support varies by cloud region and deployment type. For details, see 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 15 compute pools per application is allowed.

• Cross-Cloud Auto-Fulfillment has the following limitation:

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

• Using the LOG_LEVEL, TRACE_LEVEL, METRIC_LEVEL, and LOG_EVENT_LEVEL properties in the manifest file to set the logging and trace level 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 Snowflake Native Apps in government regions¶

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

• Providers publishing apps from government regions can only share listings within the same organization.
• Department of Defense (DoD) regions are not supported.
• Apps with containers are not yet supported in Azure government regions.

Limitations on Virtual Private Snowflake (VPS)¶

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

• Snowflake Native Apps and Streamlit are not enabled by default in Virtual Private Snowflake. To use Snowflake Native Apps 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.

Known issue with AWS PrivateLink and Azure Private Link¶

Links in email notifications from apps do not correctly link into a private link account.
