Delta Lake (Azure)

Configuration Parameters

To use Delta Lake on Azure as a destination, provide the following parameters:

Key	Description	Example Value	Required
`account_name`	Your Azure Storage account name. This is the name of the account that hosts your Delta table.	`myazurestorage`	✅
`access_key`	The access key for your Azure Storage account. Used to authenticate writes to your Delta table.	`ABC123...XYZ`	✅
`table_uri`	URI for the Delta table. Must follow the `abfs://<container>/<path>` format. For more options, refer to the delta-rs docs.	`abfs://my-container/delta/my-table`	✅
`mode`	Write mode. - `append`: Adds rows to the table. Errors if schema changes. - `overwrite`: Replaces all existing rows and recreates the table.	`append` (default) or `overwrite`	✅

The table URI must point to a valid Delta Lake table path accessible via Azure Data Lake Storage (Gen2) using the ABFS protocol.
Mage uses the delta-rs engine for interacting with Delta Lake.
If using overwrite mode, ensure downstream systems tolerate table recreation.
