Databricks does not currently provide official support to read from or write to Snowflake Open Catalog. Although Snowflake Open Catalog is compatible with the Iceberg REST catalog and open source Spark can work with it, this integration is not supported in Databricks managed runtimes. Databricks officially supports Iceberg through Unity Catalog and documented integrations only. Using Snowflake Open Catalog directly from Databricks would require unsupported configurations and is not recommended for production. For interoperability today the supported options are Unity Catalog based Iceberg sharing or data exchange through cloud storage or managed data sharing solutions.
