Apache Iceberg™ tables: ABFS write paths for Azure external volumes (Preview)¶

For Snowflake-managed Apache Iceberg™ tables that use an Azure external volume, Snowflake behaves as follows:

Before the change:

Snowflake uses the Windows Azure Storage Blob (WASB) protocol to create paths when writing Iceberg metadata files.

For example: wasbs://<azure_container>@<azure_storage_account>.blob.core.windows.net/<file_path>/

After the change:

Snowflake uses the Azure Blob File System (ABFS) protocol to create paths when writing Iceberg metadata files.

For example: abfss://<azure_container>@<azure_storage_account>.blob.core.windows.net/<file_path>/

Ensure that any external tools that read your Snowflake-managed Iceberg tables can read the ABFS paths.
